This occurs when the netCDF configure script can't figure out what kind
of fortran compiler you are using. The solution is to set CPPFLAGS to
-DpgiFortran, or -Df2cFortran (but not both at the same time) and rerun
configure.

It should work just fine, once you find the magic CPPFLAGS setting for
that compiler.

I don't know which one your compilers want in your circumstances, but
either pgiFortran or f2cFortran should work. Make sure you run make
check afterwards to be sure.

Good luck,
