Hi Maria,

It looks like the FFLAGS variable didn't get set= with -m64.

configure:24283: checking FFLAGS
configure:24285: result: -g -O2

There was a typo in the command I sent you in setting FFLAGS (sorry about that 
- need more coffee). Try:

lt_cv_ld_force_load=no CFLAGS="-arch x86_64" CXXFLAGS="-arch x86_64" 
FCFLAGS="-m64" FFLAGS="-m64"  ./configure --prefix=/home/mmartinc/local 
--disable-netcdf-4

I had FFLAGS="=-m64" instead of FFLAGS="-m64". You could also add "-g -O2" to 
each of those flags as well (e.g. CFLAGS="-arch x86_64 -g -O2").

I tested this on my mac with the same gcc and gfortran and it worked (for 32 
and 64 bit). Hopefully we can get it going for you too. I did find that if I 
removed FFLAGS, then the config failed where it fails for you.

Cheers!

Sean
