Title: gfortran: 4.7. And now builds from source.

A modification of the gcc formula that builds gcc and rips of
everything except gfortran.

We had a small discussion on the homebrew mailing list.
Here is the first version of a gfortran formula that does not suck.
By "suck" I mean download binaries of gcc 4.2 from research.att.com, un-pax, and remove all non-fortran parts.

This formula is based on the gcc formula and removes binaries other than gfortran (you cannot really build gfortran stand-alone). Because long build is loooooooong, we should bottle it.

Please let me know if this works for you. I will do some more tests the next days.
