Hi Michael:

It sounds like you have a stale cache problem from attempting to re-run
after the first error is encountered.  ccmake also has caching issues that
obfuscate problems.  Therefore, please start again in an empty build tree
following the directions above (export; cmake [not ccmake]; make; etc.).

If the problem persists, we can only help you further if you give us
complete specifics (i.e., exact export and cmake commands, full cmake output
from the time you run cmake in an empty build tree, full make output).

My personal experience is setting the FC environment variable "just works" for
systems which have either g77 or gfortran.  Other developers here have
reported good success with a number of additional fortran compilers.  Thus,
whatever the issue you are having, I feel confident we can solve it if you
give us the requested specifics.

Alan
