I have been building a test server with RedHat 7.2 to experiment with Interchange 4.8.6. RedHat 7.2 came with Perl 5.6.0, but I had to upgrade to 5.6.1 because of dependency issues with some of the RPMs that are part of Interchange.

When I upgraded from Perl 5.6.0 to 5.6.1, my PERL5LIB was apparently left unchanged. As a result, all of the entries in PERL5LIB still point to the directories for Perl 5.6.0 instead of 5.6.1.

In a situation where I was writing a very simple Perl application entirely by myself, I'd probably just do use lib qw(/usr/lib/perl5/5.6.1/i386/linux ...); and not worry about it. But it's not that simple in this case. I even have problems with Apache because when I run /usr/sbin/apachectl start, I get "Cant locate strict.pm in @INC" when strict.pm is simply in the 5.6.1 directories instead of 5.6.0.

So, my questions:

FWIW, I would not be trying to install everything using RPMs, were it not for the fact that I have to document a repeatable server build process, and other developers and system admins need to be able to follow it. Every one of the people who might follow my documentation has less experience with Perl than I do.
