29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

32 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1314 This installation shell script will examine your system and ask you questions
1315 to determine how the perl5 package should be installed. If you get
1316 stuck on a question, you may use a ! shell escape to start a subshell or
1317 execute a command. Many of the questions will have default answers in square
1318 brackets; typing carriage return will give you the default.
1320 On some of the questions which ask for file or directory names you are allowed
1321 to use the ~name construct to specify the login directory belonging to "name",
1322 even if you don't have a shell which knows about that. Questions where this is
1323 allowed will be marked "(~name ok)".
1327 dflt='Type carriage return to continue'
1331 The prompter used in this script allows you to use shell variables and
1332 backticks in your answers. You may use $1, $2, etc... to refer to the words
1333 in the default answer, as if the default line was a set of arguments given to a
1334 script shell. This means you may also use $* to repeat the whole default line,
1335 so you do not have to re-type everything to add something to the default.
1337 Everytime there is a substitution, you will have to confirm. If there is an
1338 error (e.g. an unmatched backtick), the default answer will remain unchanged
1339 and you will be prompted again.
1341 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1342 the questions and use the computed defaults (or the previous answers if there
1343 was already a config.sh file). Type 'Configure -h' for a list of options.
1344 You may also start interactively and then answer '& -d' at any prompt to turn
1345 on the non-interactive behaviour for the remaining of the execution.
1351 Much effort has been expended to ensure that this shell script will run on any
1352 Unix system. If despite that it blows up on yours, your best bet is to edit
1353 Configure and run it again. If you can't run Configure for some reason,
1354 you'll have to generate a config.sh file by hand. Whatever problems you
1355 have, let me (chip@atlantic.net) know how I blew it.
1357 This installation script affects things in two ways:
1359 1) it may do direct variable substitutions on some of the files included
1361 2) it builds a config.h file for inclusion in C programs. You may edit
1362 any of these files as the need arises after running this script.
1364 If you make a mistake on a question, there is no easy way to back up to it
1365 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1366 files. Configure will offer to let you do this before it runs the SH files.

4643 I need to select a good name for the shared libperl. If your system uses
4644 library names with major and minor numbers, then you might want something
4645 like $majmin. Alternatively, if your system uses a single version
4646 number for shared libraries, then you might want to use $majonly.
4647 Or, your system might be quite happy with a simple libperl.$so.
4649 Since the shared libperl will get installed into a version-specific
4650 architecture-dependent directory, the version number of the shared perl
4651 library probably isn't important, so the default should be o.k.
