This particular problem should now be resolved and was due to NFS disk issues on the server.  Since the question was posted anonymously it was awaiting moderator approval and we apologize for the delayed response; in the future an email to datalab@noao.edu or logging in under your user account to post questions are alternative ways to get help.
