[XeTeX] How to load pstricks?

[Sven Siegmund]

Actually I am not sure what helped. Before I tried to uninstall and
reinstall them I copied them manually in their respected location from
CTAN from the path you mentioned. They were there, but I thought I
must rebuild the FNDB and other stuff, so I also uninstalled the
package and installed it again. then it worked -- but maybe because of
the manual copying.
