You're right, it probably wouldn't have gotten that far with f2c --
it was calling g95.

From reading about the differences between g95 and gfortran, it looks
like gfortran is even less likely to support >=fortran95, but I'll try
setting PKGSRC_FORTRAN=gfortran and see if there's a difference.
Odd, I'm pretty sure I built boost successfully not long ago. I need
to find out what the circumstances where (I'm doing some major
replumbing on the build system).

.. and it's already in pkgsrc-wip. :)
