GCC 4.5 is not enough, actually. 4.6 is the least acceptable version,
if we're talking about Fortran dialect in current use.

I have to point out that GCC 4.7 didn't build for me on 6.1 RCn
for different reason until pkgsrcCon when it built the first time at all.
I had problems building pkgsrc GCC 4.7 on Debian/Ubuntu systems after

Then this is the same old problem with official bulk builds.
NetBSD 6.0 builds should be thrown away in favour of 6.1 or 6.0.2 at least
until we get enough power to support it.
My point is that if we're going to solve problems around Fortran
by forcing everyone to use modern dialect, we should solve underlying
problems first. Currently, there's a lot of packages that rely on F77
directly or indirectly. When combined with our insistance on using
libtool it causes a lot of breakage. I don't know how to deal with it,
since most reasons lie in social problems:
- NetBSD developers resist shipping Fortran compiler;
- NetBSD developers resist building packages on reasonably new releases
that contain necessary bug fixes;
- pkgsrc developers insist on using libtool;
- pkgsrc developers insist on using only post-77 Fortran with libtool
(ignoring those very reasons why the split between "fortran" and
"fortran77" was introduced).
