My original problem was an inability to generate R plots using the
following scenario:
1. HTML page sends data to Ruby CGI
2. Ruby CGI passes on data to R plotting script, which generates a plot
3. Ruby CGI passes plot back to user
With help from Scott Sherrill-Mix on this list and from a local friend
at my institution, the confusing server message I was getting went
away after fixing the permissions on the folder in the webserver
containing my code:
> sudo chmod 775 gsa
> sudo chown mrich:www gsa
