gcc can't find libs

["Austad, Jay" <austad@marketwatch.com>]

When I try to compile something using the -lGLU and -lgl flags, gcc says it
can't find those libraries, even though I have them.  I have some
precompiled binaries that are linked against them and work just fine.  I've
done an ldconfig, but I still get the same error.

Any ideas on how to fix this?  

I'm trying to make a GL clone of the game "SFcave" for the palmOS.  That
game is so addicting.
