The first problem is that /usr/local/bin/f2c can't be used directly as
the Fortran compiler; instead, use /usr/local/bin/fc which is a script
that calls f2c that should have been installed when you installed f2c.

Use of f2c instead of fc explains the above error, since f2c won't
make a ".o" file from a ".f" file.

After you change the FC environment variable, just delete config.cache
and run the configure script again.  Expect some errors in config.log;
they occur normally in compiling test programs to determine the
compilation environment before creating Makefiles.  There will be some
warning messages you can ignore.  

I just tried it on a Mac OS X 10.1.1 system with the settings:

 CC=/usr/bin/cc
 CPPFLAGS=-Df2cFortran
 FC=/sw/bin/fc         # this is where "fink" installed f2c on our system
 FFLAGS=-w
 F90=''
 M4FLAGS=''

and "make all" seemed to work OK.  To get "make test" to work I had to
make sure the environment variable FPP was unset, although we had been
recommending FPP='cc -E -C' in our INSTALL instructions.  I've just
changed the INSTALL web page to reflect this change:
