[Paraview] Bug 0006714: pvbatch requires X server

[Kent Eschenberg]

Thanks! The only reason I haven't tried it yet is that I have to finish this paper for this summer's TeraGrid conference. I'm saying a lot of good things about ParaView and mention the upcoming paper on the XT3 port. Maybe Monday.

Its great that this has already been resolved on the XT3 since that is the destination for this batch script as soon as I get it to run at least once on our Linux cluster.
