The problem is that when you did a "get" on code.haskell.org, the other
repo was /srv/code/gtk2hs, and now that you're on a different machine
that path is no longer accessible.
Either use non-lazy repositories, or pull down the whole gtk2hs
repository locally so that all the patches end up in your local cache
(~/.darcs/cache). Non-lazy repos aren't as bad as they seem, because
darcs hard-links all the patch files together.
Cheers,
Simon
