I believe I see the problem. The patch-file that you applied to the
"cfortran.h" file in order to build the netCDF package on a Mac OS X
system using the Absoft Pro Fortran compiler assumed that all Fortran
code would be compiled using the "-YEXT_NAMES=LCS" option. The CAM
package, however, requires the (default) "-YEXT_NAMES=UCS" option.
So, what we have is a mismatch between the patch-file assumptions and
your situation.
Please try the following:
1. Go to the fortran/ subdirectory.
2. Revert your "fortran/cfortran.h" file to what it was before you
patched it (you should be able to retrieve the original from the
download-file).
3. Apply the attached patch (which assumes that upper-case names
will be used).
4. Go to the top-level source-directory.
5. Execute the command "make distclean".
6. Set the following environment variables to the indicated values:
FC=/Applications/absoft/bin/f90
FFLAGS="-w -YEXT_NAMES=UCS -YEXT_SFX=_ -YCFRL=1"
F90=/Applications/absoft/bin/f90
F90FLAGS="-w -YEXT_NAMES=UCS -YEXT_SFX=_ -YCFRL=1"
FLIBS=-lU77
CPPFLAGS="-DNDEBUG -DAbsoftProFortran"
CFLAGS=-O
7. Perform steps 6 through 9 described at

Please let me know if this helps.
