| Whats wrong with shared library support on AIX?
It's a sort-of-Unixized port of OS/2 shared libraries. So you need to use
OS/2-style import files to link one shared library against another, linking
goes much more easily if you have OS/2-style export files, and all symbols
must be resolved at shared library build time, among other oddities compared
to most Unixes.
Also, shared objects that work fine on every other system I've built them
on, regardness of weirdness (such as the shared library version of netpbm
from the libgr package), build on AIX but programs using them dump core on
startup. I suspect this means static data in shared libraries behaves
strangely. (I *hope* it doesn't use the OS/2 default of "static data is
shared between processes using the shared library"...).
In any case, the Cyrus SASL libraries refuse to build properly on AIX as
distributed, and while I can get something (of unknown functionality) if I
update it to use the latest libtool, you then have to use that same libtool
version to link against SASL.

Wouldn't surprise me much; libtool can do only so much to deal with
