[netCDF #AJO-570770]: netCDF Fortran Installation Questions

Hello David,

My initial thought was that `--fflags` was deprecated, as the fortran interface 
was moved into a separate library starting with netcdf 4.2.0.  Testing locally, 
however, I see that the `nc-config` created on my system has proper information 
for nc-config --fflags.  Can you provide more information regarding how you 
built netCDF-C?  If possible, can you provide the 'config.log' file created 
when you built it?

Regarding -has-f90;  I've spoken with Russ Rew, our Fortran expert, and we 
agree that this may be a bug in nf-config.  Assuming you have an F03 compiler, 
--has-f90 would be set to 'no' even though F03 supports the f90 API.  In the 
short term, you can fix this by editing the `nf-config` script directly and 
change the value of has-f90 from no to yes.  This assumes you are using a 
compiler which supports F03.  If this is *not* the case,  the fix is even 
simpler; you will need to install a compiler which supports the f90 API.

I hope this helps,

-Ward
