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.)

1312 This installation shell script will examine your system and ask you questions
1313 to determine how the perl5 package should be installed. If you get
1314 stuck on a question, you may use a ! shell escape to start a subshell or
1315 execute a command. Many of the questions will have default answers in square
1316 brackets; typing carriage return will give you the default.
1318 On some of the questions which ask for file or directory names you are allowed
1319 to use the ~name construct to specify the login directory belonging to "name",
1320 even if you don't have a shell which knows about that. Questions where this is
1321 allowed will be marked "(~name ok)".
1325 dflt='Type carriage return to continue'
1329 The prompter used in this script allows you to use shell variables and
1330 backticks in your answers. You may use $1, $2, etc... to refer to the words
1331 in the default answer, as if the default line was a set of arguments given to a
1332 script shell. This means you may also use $* to repeat the whole default line,
1333 so you do not have to re-type everything to add something to the default.
1335 Everytime there is a substitution, you will have to confirm. If there is an
1336 error (e.g. an unmatched backtick), the default answer will remain unchanged
1337 and you will be prompted again.
1339 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1340 the questions and use the computed defaults (or the previous answers if there
1341 was already a config.sh file). Type 'Configure -h' for a list of options.
1342 You may also start interactively and then answer '& -d' at any prompt to turn
1343 on the non-interactive behaviour for the remaining of the execution.
1349 Much effort has been expended to ensure that this shell script will run on any
1350 Unix system. If despite that it blows up on yours, your best bet is to edit
1351 Configure and run it again. If you can't run Configure for some reason,
1352 you'll have to generate a config.sh file by hand. Whatever problems you
1353 have, let me (chip@atlantic.net) know how I blew it.
1355 This installation script affects things in two ways:
1357 1) it may do direct variable substitutions on some of the files included
1359 2) it builds a config.h file for inclusion in C programs. You may edit
1360 any of these files as the need arises after running this script.
1362 If you make a mistake on a question, there is no easy way to back up to it
1363 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1364 files. Configure will offer to let you do this before it runs the SH files.

4641 I need to select a good name for the shared libperl. If your system uses
4642 library names with major and minor numbers, then you might want something
4643 like $majmin. Alternatively, if your system uses a single version
4644 number for shared libraries, then you might want to use $majonly.

4647 Since the shared libperl will get installed into a version-specific
4648 architecture-dependent directory, the version number of the shared perl
