'gcc' is /usr/bin/gcc, which doesn't know where fink puts its 
libgfortran.dylib. So it is not surprising that it doesn't find it.

This is because gfortran-shlibs is a virtual package, and dpkg doesn't 
really understand Fink's virtual packages. Try 'fink list 
gfortran-shlibs'. If it has a "p" in front, it is "provided".

Disappeared a couple of years ago. It also never concerned Fink's 
compilers. You need to call gcc-4 explicitly, or better do your linking 
with gfortran. Then you don't need -lgfortran. And you won't forget 
-lgfortranbegin.
