Hello Paul,

The linker on my O2 seems to go through each library one at a time.  

CC  stuff.o -llib1 -llib2

It will look at stuff.o and create a list of unresolved symbols.  It will
then look at lib1 and see if it can resolve any of those symbols as well
as adding to the list of unresolved symbols for those routines it is
linking in.  It then does the same thing for lib2.  Unfortunately, this
means you have to put the libraries in the correct order.  

I have mine as contrib, graphics, imaging, common and that seems to work
fine.

Good luck,
Hank
