I've run into a problem when using XML::Parser under our modperl setup in production (on AIX 5.3). It works fine in development but fails on production with the following error:
[Tue Apr 03 08:44:03 2012] [error] Can't load '/wload/es1p/app/perl/lib/site_perl/5.10.1/aix/auto/XML/Parser/Expat/Expat.so' for mo

The expat/expat-devel libraries were installed into /opt/freeware/lib using a package (the same one on dev and live) and both show the same output from ldd Expat.so:
Expat.so needs:
/usr/lib/libc.a(shr.o)
/opt/freeware/lib/libexpat.a(libexpat.so.1)
/unix
/usr/lib/libcrypt.a(shr.o)
I've tried setting up LIBPATH both in our dotfiles and in our mod_env configuration but with no luck. I'm not expecting someone to know the exact answer but I've run out of ideas as to what I can try so I'm hoping for some suggestions to try out.
EDIT: I should also point out that the same script using XML::Parser works perfectly as a normal cgi-bin script on our live server.
