Geoffrey, Well the gcc4.info for the package containing gfortran in fink has...
Depends: gmp-shlibs (>= 4.1.3-11), cctools (>= 576-1) | odcctools (>= 576-200503 27), %N-shlibs, libiconv BuildDepends: gmp (>= 4.1.3-11), libiconv-dev which is a tad confusing since I guess it implies that cctools isn't needed to build gcc4/gfortran but is needed to use it. That seems weird since to build it and do a make check is to effectively use it. Jack
