29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1836 This installation shell script will examine your system and ask you questions
1837 to determine how the perl5 package should be installed. If you get
1838 stuck on a question, you may use a ! shell escape to start a subshell or
1839 execute a command. Many of the questions will have default answers in square
1840 brackets; typing carriage return will give you the default.
1842 On some of the questions which ask for file or directory names you are allowed
1843 to use the ~name construct to specify the login directory belonging to "name",
1844 even if you don't have a shell which knows about that. Questions where this is
1845 allowed will be marked "(~name ok)".
1849 dflt='Type carriage return to continue'
1853 The prompter used in this script allows you to use shell variables and
1854 backticks in your answers. You may use $1, $2, etc... to refer to the words
1855 in the default answer, as if the default line was a set of arguments given to a
1856 script shell. This means you may also use $* to repeat the whole default line,
1857 so you do not have to re-type everything to add something to the default.
1859 Everytime there is a substitution, you will have to confirm. If there is an
1860 error (e.g. an unmatched backtick), the default answer will remain unchanged
1861 and you will be prompted again.
1863 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1864 the questions and use the computed defaults (or the previous answers if there
1865 was already a config.sh file). Type 'Configure -h' for a list of options.
1866 You may also start interactively and then answer '& -d' at any prompt to turn
1867 on the non-interactive behaviour for the remainder of the execution.
1873 Much effort has been expended to ensure that this shell script will run on any
1874 Unix system. If despite that it blows up on yours, your best bet is to edit
1875 Configure and run it again. If you can't run Configure for some reason,
1876 you'll have to generate a config.sh file by hand. Whatever problems you
1877 have, let me (perlbug@perl.org) know how I blew it.
1879 This installation script affects things in two ways:
1881 1) it may do direct variable substitutions on some of the files included
1883 2) it builds a config.h file for inclusion in C programs. You may edit
1884 any of these files as the need arises after running this script.
1886 If you make a mistake on a question, there is no easy way to back up to it
1887 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1888 files. Configure will offer to let you do this before it runs the SH files.

3065 In general it is a good idea to keep gcc synchronized with
3066 the operating system because otherwise serious problems
3067 may ensue when trying to compile software, like Perl.
3069 I'm trying to be optimistic here, though, and will continue.

16516 If you'd like to make any changes to the config.sh file before I begin
16517 to configure things, do it as a shell escape now (e.g. !vi config.sh).
16520 rp="Press return or use a shell escape to edit config.sh:"
16525 *) : in case they cannot read
16526 sh 1>&4 -c "$ans";;
16531 : if this fails, just run all the .SH files by hand
16538 if $contains '^depend:' [Mm]akefile >/dev/null 2>&1; then
16545 Now you need to generate make dependencies by running "$make depend".
16546 You might prefer to run it in background: "$make depend > makedepend.out &"
16547 It can take a while, so you might not want to run it right now.
16552 rp="Run $make depend now?"
16556 $make depend && echo "Now you must run '$make'."
16559 echo "You must run '$make depend' then '$make'."
16562 elif test -f [Mm]akefile; then
16564 echo "Now you must run a $make."
16569 if $test -f Policy.sh; then
16572 If you compile $package on a different machine or from a different object
16573 directory, copy the Policy.sh file from this object directory to the
16574 new one before you run Configure -- this will help you with most of
16575 the policy defaults.
16579 if $test -f config.msg; then
16580 echo "Hmm. I also noted the following information while running:"
16582 $cat config.msg >&4
