# [Xy-pic] XYpic oztex driver option problem

 I use oztex 4.0 running on an iMac, system 9.1. I use xy-pic to make
diagrams and the like and also use special features that require the
PostScript back end to work such variable line thickness for example.
I managed to make a .ps file that prints correctly by invoking
\xyoption{ps} and \xyoption{dvips}. However, the
correct pictures do not appear in the OzTeX dvi viewer, also not when
I invoke the \xyoption{oztex}.
In particular the following error message is produced:

(SystemDisk:Applications:tex:Packs:Xy-pic:xyps-r.tex)
! Undefined control sequence.
\installPSrotscale@ \xyPSsh...

l.31 \begin{document}

?
(SystemDisk:Applications:tex:Packs:Xy-pic:xyps-l.tex)

This also happens even with an empty document.

Anyone familiar with the problem and solved it?
