That is because your C code must have been compiled without -fPIC or 
-mcmodel=medium

That is because your NetCDF library was compiled without -fPIC or 
-mcmodel=medium

The first problem is very easy to fix, the latter is more difficult as it 
would require your sysadmin recompiling NetCDF (or you can do that yourself).

Please use the newly checked in optfiles:
linux_amd64_ifort (serial)
linux_amd64_ifort_generic_mpi (parallel)

For the latter you need to define an environment variable 
MPI_INC_DIR=/usr/local/topspin/mpi/mpich/include
in your case before calling genmake2.
