It is probably overkill, but you can take a gander at the Makefile.am 
Makefile.in configure and configure.ac in:

http://www.netperf.org/svn/netperf4/branches/glib_migration

for examples of what may not be pristine, nor adhere to chapter and 
verse, but seem to be functional use of libtool with automake et al and 
GModule.

One thing I've just learned getting netperf4 to work on Linux, HP-UX, 
AIX, MacOS X and Windows is that "g_module_open means never having to 
include the suffix" so you can, and perhaps should (?) drop the ".so"
