[netCDF #GNF-884914]: Error: netcdf-4.2-snapshot2012021222

Hi Craig,

Did you run "make check" on HDF5, and was it version 1.8.8?
I've found that "make check" fails using the llvm-based C compiler that 
comes with the Xcode-4.2.1 developer tools, but that if you build with
the gcc-4.6 that is available from Macports, the HDF5 library passes all
the tests from "make check".  I haven't had a chance to check if the 
resulting library works with the latest netCDF-4.2.snapshot yet.

I wouldn't advise proceeding without knowing which test in tst_files4 failed,
and that would require duplicating the problem and doing some debugging.  
Sometimes the problems are in the tests, but more often they indicate a real
bug.  Which exact version of netCDF are you using, netCDF-4.2-rc1 or the 
daily snapshot?

It looks like you're using ifort, and the error is

> Undefined symbols for architecture i386:
>  "_netcdf_mp_nf90_create_", referenced from:
>      _MAIN__ in f90tst_vars.o

Can you see what architecture f90tst_vars.o is compiled for, using

  otool -L f90tst_vars.o

Are you using the procedure described here for building the separate
Fortran library:
