It doesn't compile - that's what's broken :). My impression is that  
there is quite a bunch of new pieces and changes in the C back-end  
code that were shared by the gfortran, but the fortran part was not  
updated correspondingly. I tried to patch some of the holes, but  
didn't get very far. Maybe if someone has the spare time to trace all  
the changes individually in both the FSF and Apple branch could put  
it together...

The problem is Apple doesn't support gfortran and never did. The  
ability to compile gfortran from the Apple branch was just incidental  
and required some tweaking as well (basically manually enabling f95  
in the build script and patching together fat gfortran libraries),  
but it was harmless. When you ask them, they say "use f2c" (but R  
doesn't support that).
