Those errors indicate that the C netCDF library is not being linked.  You need 
to
use instead:

  NETCDF_LIBS=-I$(NETCDF)/include -L$(NETCDF)/lib -lnetcdff -lnetcdf

It would definitely be shared with the latest release, netcdf-4.2.1.1, but 
with 4.1.2 it may have been created static only, or without the information
included about where the C library could be found.

If you use the above and get other unsatisfied externals, you'll need to
add more libraries, such as -ldap -lcurl -libz.
