I recently installed 1.5 on a Dell OptiPlex GXa, and on a Toshiba
Tecra 510 CDT.  Both installs are from the same Wasabi CD.

Ghostscript -- from the packages collection -- works on the Toshiba.
It does not work properly on the Dell.  When I call gv test.ps, for
example, I see

  Unrecoverable error: invalidaccess in put
  Operand stack:
    --nostringval--  estack  --nostringval--  --nostringval--  $error
    --nostringval--  savedlocaldicts  --nostringval--  false

The same message appears on printed output, ahead of the correctly
displayed postscript.  

Can anyone suggest what is going on?  I have already tried reinstalling 
ghostscript on the Dell -- 

Thanks!
