Bugzilla Bug 52279

On my system the latest hdf fails to compile:

g77  -Wsign-compare -O3 -fomit-frame-pointer -c -o df24ff.o `test -f 'df24ff.f' || echo './'`df24ff.f
/bin/sh: line 1: g77: command not found

!!! ERROR: dev-libs/hdf-4.2.0-r3 failed.
!!! Function src_compile, Line 31, Exitcode 2
!!! emake failed

If I'm not mistaken, this is because I don't have 'f77' in my USE flags and hence g77 is not build when gcc is merged.

Yes, you're right, and until there's some change in portage there's no clean
way to handle this. Maybe I'll add a warning tomorrow.

Dies now if it can't find g77. Regarding this as fixed until there's a portage
feature for this kind of problem.
