The scheme graphics package has given us problems in the past on machines 
outside the lab.  It seems to expect to have available for itself a fairly 
large color map so if you are getting errors you might try quitting netscape 
or removing background pictures and restarting edwin.  If you still have no 
luck you should come to lab, we're sorry but we do not really suppost scheme 
outside of the lab.

You may need to edit the file ps2go.scm to give it the locations of the 
other files
