Hi All, Though I am not into compilers to deep, I have been thinking about of the problems with pyx-numpy. Would it not be easier to have all things needing Fortran run over the g95-compiler than the full gcc version distributed by Macports. Or does the g95 fortran compiler suffer from the

A few thoughts: (1) Where does /usr/bin/gfortran come from? There are a number of numpy tickets open (and closed) where this executable has been installed. numpy's internal configure routines will discover it, and it causes issues. Apple's XCode does not install a fortran executable, so it
