Perl include directories no longer work in mod_perl

We just did an upgrade from Centos 5.5 to Centos 5.7 and it seems like the
extensions we added to the Perl library directories stopped working:

 

[Fri Dec 23 16:40:04 2011] [error] Can't locate Config/Simple.pm in @INC
(@INC contains: /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl
/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi
/usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl
/usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .
/etc/httpd)

 

We've been adding to the library path through /etc/profile:

 

LIB_LOCAL=/opt/custom/local

PERL5LIB=${PERL5LIB}:$LIB_LOCAL/lib/perl5/site_perl/5.8.8/i386-linux-thread-
multi

PERL5LIB=${PERL5LIB}:$LIB_LOCAL/lib/perl5/site_perl/5.8.8

 

And it looks to be fine:

echo $PERL5LIB

:/opt/custom/local/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi:/opt/cu
stom/local/lib/perl5/site_perl/5.8.8

 

It's been working fine until this upgrade to Centos 5.7.

 

Please advise.  Any help is appreciated.

 

Thanks,

M
