Thanks Foxcub!

hmm I was seeing just a small amount of PS code so I created 
a little test code as you suggested and it did not work either.
So, after a little routing around, it looks like you nailed it; 
a bad TK install.  I forgot to complie the c routines. I could still
use most of the canvas features except the ps dump.
Feeling pretty foolish now.

Thanks again.
