Nope, perl is totally self-contained, there are no '.conf' files etc.
As for man pages, you CAN fix that if you know where they are and put in the
right settings, but of course perl itself doesn't depend on or care about man
anyway, so its not going to break any functionality, and on top of that if
its the same version of perl then the man pages shouldn't be different anyhow
;o).

Perl is designed to 'just work'. When you use the CPAN tool or hand invoke the
MakeFile.PL for a package it will ask perl to tell it where perl is
installed, etc. There is actually a module called 'Config.pm' who's function
is to do all of that, so any program can 'use Config;' and learn all about
where perl is installed and how it is configured, right down to the compiler
flags used, version of linker, etc! Do a 'perldoc Config', its says:
The Config module contains all the information that was available to
the "Configure" program at Perl build time (over 900 values).
Shell variables from the config.sh file (written by Configure) are
stored in the readonly-variable %Config, indexed by their names.
etc.

Well, perl people have settiled on either /usr/local (so you have
/usr/local/bin/perl and /usr/local/lib/perl5/...) or just plain /usr/bin and
/usr/lib (since at this point Perl is NON OPTIONAL on most systems, try
running Mandrake without it for instance, good luck).

Cheer up, its a cranky thing, I just rebuild Apache from scratch, big deal
;o).

Python is nice, I just long ago decided to stick with Perl since they are
basically 6 of one and half a dozen of the other. Besides, Python doesn't
have AxKit! :o).
