Thanks. Your feedback is very welcome.

I have updated the code to not relay on hardcoded library extensions.

It wasn't really necessary to call these functions from C so I have
removed the code doing this. Although the problem may reappear later in
the build process.

Until the long-awaited full introspection becomes available i GLib, clg
uses nm to find all types in a library by searching for symbols ending
with _get_type. The cause of the problem above is that nm doesn't take
the same options in OSX as the GNU nm. I have checked in some untested
code that may solve this. It would be nice if you could test it again
and report back to the list.
