I don't object to the patch, but I'm working on removing 
f2c, libf2c, and f77 from the base distribution.  I have
f2c and libf2c building within the ports framework, and
I've written a new f77 wrapper.  I should have the work
done and tested in the next week.  The new wrapper has some
desirable features that can't be easily integrated into the
current f77(1).
