gcc bug or missing libraries?

["Jonathan Hays" <jhays at acropolis dot com>]

Sorry if this is a dumb question but I'm pretty new to gcc. I've already
tried putting most of the libraries I can think of in my LD_LIBRARY_PATH
but gcc won't link (compiles okay, though). Maybe someone could just
point me in the right direction, like "This is a common problem - go
read the XYZ documentation".

Thanks in advance,

Jonathan
