[darcs-users] darcs does not install in a fresh sandbox

Hi Dominic,

I think you're using GHC 7.8, which isn't supported by darcs 2.8 -
obviously the error here could be clearer!

Darcs HEAD does build with GHC 7.8, at least on Windows, but there may
be a serious bug with the filesystem handling for an as-yet-unidentified
reason, so I would recommend against trying it for now.

I'm not sure if we want to spend the effort supporting GHC 7.8 for the
2.8 branch - do you have a particular reason to need this?

Cheers,

Ganesh
