222	Hackage should be able to track which version of package is compatible with which version of GHC	guest		"This is related to ticket #221 and #199. Cabal-install at this time always fetches the highest version of a package. But the highest version may not be compatible with the version of GHC.

The example is the HXT package.

As of this writing, version 7.4 is for GHC 6.8. But for those who have GHC 6.6, version 7.3 should be fetched. If there is a flag in Hackage to indicate this compatibility matrix, then cabal-install can make correct decision which version to fetch based on the GHC version the user has.
