Well, I repeat a post from me in April here:
There have been quite a few problems getting modperl and assorted
sub-modules to work since the change that httpd uses the AIX native
dlopen under AIX 4.3 and above. In particular this conflicts with perl,
as this still uses the dlopen emulation code. Older AIX versions where
both httpd and perl use the dlopen layer are not affected.
I have put together a patch to Apache, perl and modperl that also turns
on runtime linking (-brtl), which makes the AIX dynamic loading behave
more like the ELF style dynamic linking. In particular this fixes
problems with modules like Apache::Request and HTML::Embperl that need
to reference symbols from both httpd and modperl with modperl either
linked statically into httpd or as DSO.
Perl after this patch also uses the AIX native dlopen, thus if you need
binary compatibility to older compiled perl modules do not use this
patch. The dlopen emulation code used deferred imports which the native
dlopen does not handle.
The patch is in three parts and can be found at:
<http://www.han.de/~jum/aix/>
download the following files:
apache_1.3.19.rtl.patch
modperl.rtl.patch
perl-5.6.1.dlopen.patch
The apache_1.3.19.rtl.patch does also apply to 1.3.20 cleanly.
