I looked into the problem and found a fix.  Add the following lines to
ps2bits, right before the line that says "end definepackage
beginpackage".  By the way, this is for educational purposes only,
don't actually *use* it, because certain managers at Sun don't want
you to get the most out of OpenWindows, and you might hurt their
feelings.

Oh hell, here's the whole fixed ps2bits script, in case you don't have it.
