[netCDF #AIX-484936]: netcdf-4.1.2 build error

Greetings Irena!

`make check` is looking for nf_*_ symbols (e.g. nf_open_) but can't find them 
because they are set as nf_*__ (two appended underscores instead of one). It 
may be the case that the configure script does not recognize `gfortran4` and is 
not able to set the proper flags. Try the following:

make distclean

export CPPFLAGS=-DgFortran

and then run config, make, and make check.

Also, is gfortran4 the name of the actual fortran compiler, or is it a symlink 
to a specific version of gfortran (ls -l /usr/pppl/gcc/4.6.0/bin/gfortran4 will 
tell you)?

Thanks!

Sean
