I did not yet try to compile mod_perl into Apache statically, so I am
not 100% sure why you get unresolved symbols, it would be interesting to
see which ones are unresolved. There are actually two ways to do dynamic
linking under AIX nowadays, namely the classic AIX way that was
available since AIX 3.1 (uses export files like under Windows or OS/2)
and for System V compatibility the runtime linking style which more or
less is like ELF dynamic linking used under Linux or Solaris. Both
Apache and Perl are only doing the classic AIX style dynamic linking, so
you cannot use the Linker Option -G to turn on runtime linking for a
module, you must use the -bE:export file -bM:SRE options instead. The
option -berok may not be used with the classic style dynamic linking,
this is causing the segfault here.
