Well, it seems you were right: I updated the $PATH variable and now I can read PS files (the error messages in my first post were copied before I changed the GhostView settings). Unfortunately, a problem solved means a new problem (2, in fact): whenever I open a PDF file I get the following rather complicated message:
Error: /invalidfileaccess in --file--

And more annoyingly, the $PATH variable is reset each time I start X11. I guess there is a file somewhere that contains $PATH and must be updated?
