Hi,

as most of you do not like to have fortran enabled by default, we tried
to find a way around. We created a virtual/fortran which should depend
on a working fortran compiler so that only ebuilds which need fortran
compiler will build it. With that situation it was possible to remove
USE=fortran from the profile (btw profiles cannot have a version bump
and don't need it) so that most of you could drop the fortran support
from gcc except a ebuild depends on it.

However I wasn't aware that there is no hierarchy in the dependencies in
an ebuild and portage will choose a solution w/o a USE change first.
That is the reason why many of you saw that ifc should be installed,
instead of gcc with USE=fortran. That was the point where I added it
back to the profile as a default enabled USE.

The solution for the average user is leaving all default USE on. This
will gcc build the fortran support and you will have no problem. (Libs
and compiler are 1.5MB on my system)

Or remove add -fortran to your make.conf and add sys-devel/gcc fortran
to your /etc/portage/package.use.

Trying to avoid any fortran at all is stupid, because as already
mentioned many math operations are faster if programmed in fortran.

Cheers justin
