Resolve Cabal conflicts with Yesod, EclipseFP and Haskell Platform 2012.2

Question

I've tried to install Yesod / EclipseFP / Haskell Platform 2012.02 on two Ubuntu machines.

Is this possible?

(I'm new to Yesod/Haskell and can't interpret the errors, other than they look like two things require incompatible versions of other things.)

Which project is the cause of the issue? (i.e. Who can I ask for a fix.)

cabal install yesod-platform

Answer 1

I'm getting everything to build on a CLEAN install (no previous yesod platform). I've installed the Haskell Platform, BuildWrapper, Scion-browser and yesod-platform. It seems it installed http-conduit-1.4.1.7, though, so maybe 1.4.1.8 is incompatible? Anyway, there is nothing stopping you going ahead with the install with --force-reinstalls, and then reinstall persistent-sqlite and scion-browser. Only if reinstalling these breaks yesod is an issue...
