Perhaps a better solution is for cabal-install to choose the version of the Cabal library differently. Of course it has to be within the hard constraints specified in the .cabal file and on the command line. But after that perhaps it should prefer the version of the Cabal library that it itself was built with and at second preference the latest version in the same major series. The last preference would be as now, the latest version available.

Sound sensible?
