The UDUNITS package has two major versions: the original UDUNITS (aka UDUNITS-1)
and the new UDUNITS-2 version.  The UDUNITS-2 C API differs from the UDUNITS-1
C API, although the latest version 2 release does contains a thin implementation
of the version 1 API.

I suspect that the NCO package uses the UDUNITS-1 API and the error message you
saw resulted from the installation procedure not finding the UDUNITS-1
database file, udunits.dat.  The UDUNITS-2 package uses a different database.

If I did my job correctly, then you should be able to link the NCO package
against the UDUNITS-2 library and everything should work.  Please let me
know if this isn't the case.

The alternative would be to install the UDUNITS-1 package.
