Quoting "Allen S. Rout"
$ darcs get http://code.haskell.org/XMonadContrib
Got the 'hash' message too, and also:
Thanks for the reminder. It looks like community.haskell.org has upgraded their darcs version, so we can finally fix this problem. I don't have commit bit on the xmonad repo, but I do have commit bit on the xmonad-contrib repo. Unless I hear complaints in the next, say, week, I'll upgrade the xmonad-contrib repo. I'm marking it on my calendar for November 16th now.
Warning: CRC errors found. These are probably harmless but should be repaired. See 'darcs gzcrcs --help' for more information.
Fixed. Again, thanks for the reminder. Everyone who cares about this warning should now run darcs gzcrcs --repair in their local XMonadContrib repository. You should not ever need to do this again, nor should new users who get a fresh copy of the repository (starting today) need to do this. ~d
