Yes, if you are only building and installing the netCDF library for
use with GMT, which as far as I know does not use the C++ or
Fortran-90 netCDF interfaces, you can specify not to build and install
those interfaces by setting the appropriate environment variables
before configuring and building the netCDF library:

  F90=''
  CXX=''

You can rebuild the library without these interfaces by removing the
"config.cache" file, invoking "make clean", setting the above
environment variables explicitly to the empty string, and then
re-invoking the "configure" script.

The C++ support will be fixed in the next release to work with
standard++ C compilers that use namespaces.  If you still need the C++
interface, write back telling what version of "g++" you are using, and
I'll try to provide the fixes needed to compile with that version ...
