Recompiling with dl_dlopen.xs instead of dl_aix.xs caused 49 of the 180
self-tests to fail. I recompiled with debugging turned on and ran against
GDB. Here's the result followed by the output of './perl -I./lib -V'.
Jens, did you have success running with dl_dlopen.xs without other
modification?
Regards,
Christian
