Al's problem turned out to be a bug in 'grImport', so one thing you can 
try is to install the latest version of 'grImport'.

If that still fails, you might be able to get more information about the 
problem by looking at the end of the XML file that is created by 
PostScriptTrace().  If ghostscript has hit trouble it's error messages 
will hopefully be at the end of that XML file.
