========================== My first attempt =============================
setenv CC "gcc-mp-4.7 -m64"
setenv FC "gfortran-mp-4.7 -m64"
setenv F77 "gfortran-mp-4.7 -m64"
setenv F90 "gfortran-mp-4.7 -m64"
./configure --prefix=$HOME/mpi3gnu473 --enable-fc --disable-cxx --with-device=ch3:nemesis
...
configure: ===== done with src/openpa configure =====
...
configure: error: F90 and F90FLAGS are replaced by FC and FCFLAGS respectively in this configure, please unset F90/F90FLAGS and set FC/FCFLAGS instead and rerun configure again

	Remarks: While odd, this is at least says what it wants.

========================== My second attempt =============================
unsetenv F77
unsetenv F90
./configure --prefix=$HOME/mpi3gnu473 --enable-fc --disable-cxx --with-device=ch3:nemesis
...
configure: ===== done with src/openpa configure =====
...
configure: error: ****  Incompatible Fortran and C Object File Types!  ****
F77 Object File Type produced by "gfortran   -O2" is : : Mach-O object i386.
 C  Object File Type produced by "gcc-mp-4.7 -m64    -O2" is : : Mach-O 64-bit object x86_64.

	Remark: sometimes I see "gfortran", sometimes I see "gfortran-mp-4.7 -m64"

========================== My third attempt =============================

setenv FC "gfortran-mp-4.7"
setenv FCFLAGS "-m64"
./configure --prefix=$HOME/mpi3gnu473 --enable-fc --disable-cxx --with-device=ch3:nemesis
...
configure: ===== done with src/openpa configure =====
...
configure: error: ****  Incompatible Fortran and C Object File Types!  ****
F77 Object File Type produced by "gfortran   -O2" is : : Mach-O object i386.
 C  Object File Type produced by "gcc-mp-4.7 -m64    -O2" is : : Mach-O 64-bit object x86_64.
		Remark: Well, that didn't help.

========================== My workaround =============================
In the end I created a csh script called gfortran at the start of my path and simply made it execute
	gfortran-mp-4.7 -m64 $argv
This built okay and runs just fine.
