Comment (by kencu):

 I think you need to check out `gfortran` here and see where it is going
 wrong. Try to compile a very simple fortran program, `hello.f`:
 {{{
        program hello
           print *, "Hello World!"
        end program hello
 }}}

 be careful, fortan for me was a bit touchy. There are tabs at the start of
 each line, or it doesn't compile. I know nothing about fortran coding, but
 I do know compilers now.

 Then compile it with:
 {{{
 /opt/local/bin/gfortran-mp-9 -v -o hello hello.f
 }}}
 and try to run it if it compiles
 {{{
 ./hello
 }}}

 I get this, with lots of debug info, on 10.6.8 with gcc8:
 {{{

 And from this, you should see where `gfortan` is going wrong.

 For now, I'm sticking with my "buildbot builds it differently than your
 system" theory, but paste back your errors.
