If you'd use the Prefix toolchain, you could also do all fortran stuff
on OSX, since the Prefix gcc-apple has Fortran added :)

The aim is to keep the size around that of Sage, 325 MB tarball with all
sources [1] or 469 MB lzma 64-bit linux binary. This is already
difficult, including the toolchain would make it impossible.

Sage distributes g95 and gfortran binaries for OSX. I tried to use a g95
binary on the 10.5 PPC box mentioned above. It insisted on using
libtool installed on the host which was too old and couldn't handle
some of the options g95 gave. I might have to give gcc-apple a try
after all.
