Well, I run MacOSX 10.5 on my PPC (G4), and I have gfortran. I would propose dropping support for g95... E.g. it only causes a headache when updating packages that are supposed to depend on it, e.g. cvxopt. I have no idea how and where to test my new cvxopt-1.1.2 spkg with g95... > > > Since ATLAS is not installed on OS X, it seems even less worthwhile having > > such > > a test in the ATLAS package. > > True; we use the system one. > > Sage also needs fortran for R, at least.
