Hi,
Just a heads up that ghc-7.6.3 (Haskell compiler) from F20 was built for EPEL 7 Beta last week. Lot of building of Haskell packages still to be done there.
Current EPEL versions are:
EPEL5: ghc-7.0.4 (recently updated) EPEL6: ghc-7.0.4 (updated in 2012; update to 7.4.2 planned) EPEL7: ghc-7.6.3
We will probably stay with 7.6.3 in EPEL7 at least until after ghc-7.8 is completely stable (ie when rawhide moves to 7.10+) and works on ppc64.

ps I would also like to add Software Collections for different ghc versions for EL to better allow users to choose the version of ghc best for them.
