Yes, this is really necessary.  The gcc40 port was built so you would  
have a gfortran that is
ABI compatible with your gcc and g++.  Apple does not supply gfortran  
so MacPorts has to build it.
(And Octave really does have modules written in c, c++ and fortran :-) )

The Octave port uses Apple's gcc and g++, which means it may well  
fail to build when Apple's
compilers move from 4.0.x to 4.1 or 4.2.  The R port takes a more  
conservative approach
and builds with gcc, g++ and gfortran from a single release.  We used  
to have a fortran only
port (g77) but there were endless problems in getting executables to  
link properly with modules
compiled by different version of Apple's compilers.

Best Wishes,
Greg
