It's spelled FORTRAN if you're old enough ;-)

If you happened to upgrade -current in a certain window, "make
delete-old-libs" would remove the necessary libraries, even though "make
delete-old" didn't know that it should delete /usr/bin/f77, so the
lapack build would bail out because f77 couldn't find libg2c.
Setting FC=gfortran42 is is sufficient to get lapack and
math/atlas-devel to build, assuming that lang/gcc42 is installed.
BTW, math/atlas* has been using the combination of gcc34 and
gfortran42 on -current for a while now, which means that it requires the
installation of two different gcc ports ...
