fortran spkg will go away).
Agreed, which is why I would like only fortran to be built if it is the
only language needed.

(as opposed to using XCode 4 with many packages compiled with -O0)
outweighs the "minus" of 25 minutes longer build time.
I think this is something that should be brought to the listserv. Once I
get a clang port up and running (which shouldn't be too bad on osx, since
atlas looks like it will be the only package that is going to be hell to
port), this can be resolved by changing the default compiler on osx to
clang.

I'm not sure about this, I'm using a mixture of clang (which dumps its
version as 4.2.1) and gfortran-4.5.3, and occasionally gcc-4.2.4 and
g++-4.2.4 to build sage, and currently the entire test suite is passing.
