I installed a new version of dataviewer (2.3.2), and at the same time fixed the NDSSERVER issue we were having with cdsutils.  They should both be working now.

The problem turned out to be that I had setup our dataviewer to use the NDSSERVER environment, whereas by default it uses the LIGONDSIP variable.  Why we have two different environment variables that mean basically exactly the same thing, who knows.
