You'll have to build and install the netCDF library twice: once as a
32-bit library and again as a 64-bit library.  Make sure you do a "make
distclean" between builds.  When you build the 64-bit version, ensure
that the relevant compilation environment variables have the appropriate
64-bit options.  When the first library is installed, rename it
appropriately (e.g. "libnetcdf32.a").  Do the same with the second
library (e.g. "libnetcdf64.a").  Make sure your programs reference the
correct library.
