Replying to myself (sorry).

Something else to ask... Do you run a redhat system. I noticed the
references to /usr/local, and thought maybe gnome was installed to
/usr/local when the rpms were in /usr. This could cause gnome-config
to ignore /usr/lib and look in /usr/local/lib instead.

So, Red hat? If so, you could edit the makefile line and add
-L/usr/lib after the `gnome-config --libs applets` bit.

Just guessing though ;)
