libtool, at least until quite recently, didn't do a very
good job with AIX,  so maybe yes... Actually, there were
also some problems with getting dlloaded modules built
to work with libgmodule on AIX, so I'm not sure gmodule
work even if it links.

But one thing you can try is removing the '#' in the
following line in gmodule/Makefile.am and then re-running automake,
reconfiguring and rebuilding. (See the file HACKING for
instructions on getting automake). 

===
libgmodule_la_LIBADD = @G_MODULE_LIBS@ # $(libglib)
# we should really depend on $(libglib) for libgmodule.la, but libtool has a
# problem with this ;(

That might just work with the latest versions of libtool.
