Thanks for looking at this. I upgraded to 99.1.1 (although the tar file
was named 99.1.2) and I got the same error message. When I played with
the ps.usedistiller option I found it only doesn't work when I set
ps.usedistiller to xpdf. With False or ghostscript it works ok but gives
me output with different page sizes. AFAIK xpdf is the way to go for
publication quality graphics. Do you know how I can get it to work? Is
it worth trying the svn version?
Thanks,
John.
