A short while ago the Apache distribution did change over to the native
dlopen library if the AIX version 4.3 and above. For previous versions
the dlopen emulation layer is still used. Perl does always use the
emulation, which produces a conflict if Apache uses the native one in
the modperl case. I attach a patch below that changes the perl
distribution to also use the native AIX dlopen on AIX 4.3 and above as
in the Apache case.

For getting some more involved modperl modules like Embperl to work we
probably need to change the modperl.exp file to include the magic "#! ."
instead of simply "#!" at the beginning, this signals the native dlopen
to import symbols from the main program. The patch already does that in for the perl.exp file, but only on AIX 4.3 and above because
the older AIX linkers do strange things if this option is used.
