The one trick that finally enabled me to get mod_perl to
work as a DSO with IBM's WebSphere on AIX was a utility
named rtl_enable. There were a few changes I had to make
to one of mod_perl's makefiles (apaci/Makefile, I think) to
get libperl.so to build, but even then httpd would segfault
as soon as mod_perl attempted to load a perl XS module.
But, now I run 'rtl_enable libperl.so', then replace libperl.so
with the file that gets generated. I still have to be careful
about what I put in startup.pl, but at least it works.
Perl 5.005_03, mod_perl 1.24, IBM C for AIX 5.0, and
WebSphere 2.02.
