I'm very sorry. It seems that an error occurred in Sup. Please
accept my sincere apologies. If you don't mind, please send the
-contents of sup-exception-log.txt and a brief report of the
+contents of ~/.sup/exception-log.txt and a brief report of the
circumstances to sup-talk at rubyforge dot orgs so that I might
address this problem. Thank you!
William
