Yes. GDS 2.0 needs GrADS 2.0 -- this is because of ensemble dimension  
handling. Also please note this caveat from the GDS web page:

Important Note for GDS Administrators (June 2009): A recent release of  
GrADS (version 2.0.a6) implemented some necessary changes related to  
the handling of undefined values. These changes can affect the GDS. If  
you are administering a GDS version 2.0 with GrADS 2.0.a6 or higher  
behind it, then a 1-line patch is needed for the file $GDSHOME/scripts/ 
subset.gs. The patched version is here. Updating the subset.gs script  
does not require a reinstallation or even a reload of your GDS.
