Dear Wallace,
Thanks for the tip, this patch to my Makefile fixed it:

Shouldn't this be made clear in some of the GTK+/Glade documentation? I
have the official GNOME developers guide, and had all the major web
documentation open, and nothing seems to mention this necessity.
I know to some of you longtime C hackers, this may seem like a "basic"
fact about gcc and shared libraries, but for someone who hasn't done
years of C coding in the UNIX environment, it sure doesn't come as
obvious.
Thanks a bunch,
-Andrew
