[Haskell-beginners] Beginner trying to install Haskell support in Eclipse and failing

[Graham Lowe]

As luck would have it, I ran into the same issue today. I checked the
scion google code website and found a solution. Quick summary: you'll
have to pull changes from the development branch.

Here's a link to the reported issue and the solution:

http://code.google.com/p/scion-lib/issues/detail?id=38&can=1&q=build

Hope that helps,
Graham
