[rt-users] Trying to install/run RT with 2 Perls - Redhat Perl and self installed Perl

[John Seto]

Hi all

Scenario:

Server - 64 bit RedHat 5 Enterprise with Perl and Apache provided (no
hand in this setup)

RT Version: 3.6.3
Perl Version: 5.8.8

Background:
I have successfully setup RT 3.6.3 in this environment by satisfying the
dependencies against the system Perl (installing from CPAN). RT is
running Apache and mod_perl.

The goal of this project is to create an RT setup that runs against a
local Perl version installed in /opt and has its Perl dependencies
satisfied there as well. The concern of the sys admins is that periodic
Red Hat patches will 'break' RT and the hope is that this proposed RT
setup will avoid against that possibility.
Disclaimer: I'm a relative Perl noobie.

Progress:

To avoid against the possibility of polluting the system Perl libraries,
I build Perl as non-root in /tmp and satisfy RT dependencies via CPAN
there. This goes smoothly. I also ensure that @INC is modified at Apache
startup to append the local Perl library paths at the front of the @INC
array.
I did this by having a PerlRequire startup.pl statement in the config
file and the startup.pl containing use lib qw(paths to search).

Roadblock:

Starting apache fails. I have tried rebuilding Perl several times with
different flags/switches off/on. The error message I always get is:

[Wed Oct 29 15:24:02 2008] [error] Can't load

Googling about PL_curpad is not helpful and I've searched the RT-user
archive to no avail. I'm suspecting the system Perl and the local Perl
are not getting along but I have no clue how to proceed from here. To
reiterate, I'm a Perl noobie.

Thanks in advance for any help or insights.
