The UDUNITS package is independent of the netCDF package and
vice-versa.  You can obtain the UDUNITS package at the following URL:

Hmm... I don't recognize any of the above error messages as pertaining
to the UDUNITS package.

> Can you tell me anything about "udunits" ??

I can tell you everything about the UDUNITS package (I created it :-).

If the MOM 2 model uses the UDUNITS package, then you'll need to install
it.  Get it from the above-mentioned URL and following the instructions
in the INSTALL file.

Contact me if you have any problems or questions.
