I suspect having both -Df2cFortran and -DsunFortran included in the
CPPFLAGS is a problem, as these indicate different, and possibly
conflicting, conventions for calling C functions from Fortran.

A report from a user of a build that works for Sun Studio 12 compilers
for netCDF-4.1 is here:

  http://www.unidata.ucar.edu/netcdf/docs/other-builds.html#sunstud

Note that if you get the latest source version 4.1.1

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4.1.1.tar.gz

and build it on a platform that has no HDF5 library installed or by 
explicitly specifying "--disable-netcdf-4", then it will build just 
the netCDF-3 APIs, such as were provided in version 3.6.3.  Several 
bugs have been fixed since the release of 3.6.3, and there have also 
been some portability fixes, so it may work better for you.

Please let us know if the above ideas don't solve the problem.
