These are the packages that I would merge, in order:

Hopefully the gcc guys will get the "f77" flag set on by default before they
unmask it.

Add "f77" to your useflags and remerge gcc. That should allow you to procede.
I added a conditional warning to app-sci/octave in case g77 is missing.

I only added a warning, as there are more fortran compilers than GNU Fortran !

@Phosphan: I just saw that I'm some minutes too late *G

Well, AFAICSee we only have ifc in the tree (that is in addition to the gcc),
oh and cfal, but that one will only work for Alpha. For the general population
there are mostly these two and IIRC ifc requires somewhat different invocation
parameters for the most part. Meaning it has to be processed in a special way,
like
if use ifc ; then
   ifc invocations or patches
else
   g77 "standard" procedure
fi
or some such.

I am about to add ifc to use.desc, as it is already used by blas-reference and
lapack-atlas (both masked atm, but if you would like to use this flag I can go
right ahead with adding it). So you might consider adding a pkg_setup thingy
like lapack-atlas does. In such case just let me know and I'll add the ifc
flag.

George: I copied that lapack-atlas check routine over to octave ebuild, as well
as the new ifc useflag and its dependency.

Closing, this seems to have been resolved quite a while ago (see
