[darcs-users] fromJust error in darcs-2.0.0

[Greg Holtz]

I don't know much about autoconf and how to modify it, but I'll
look into learning. I've been using darcs-2 and it seems fine.
I'd be glad to help get darcs2 opensolaris friendly.

and the latest sources of ghc (6.8.2-20080420) does not fix the
getSymbolicLinkStatus issue.
