Kevin, what version of cabal install are you using?

cabal-install version 0.8.2 using version 1.8.0.6 of the Cabal library

I ask because prior to the 1.10.* version series, cabal would have a much harder time "correctly" choosing versions of dependencies, which at least for me often manifested as such confusions in caba regarding selecting versions. Prior to said cabal version the solution I'd often do is figure out what the "transitive " dependencies were, recompile them together, iterate that, and that would eventually make the problems go away.

point being: the issue is probably conflicting versions of the same libraries are being used by different libraries that are among the dependencies, and cabal is getting confused

Is it safe to upgrade cabal-install and the cabal library or are those part of the GHC package and I'll end up making things even worse? I may have corrupted libraries; I think a re-install is in order soon, but I've been avoiding that until I get to the end of my current activities. -KQ P.S. I send Rogan the output he requested below privately to avoid spamming this list.

With --verbose=3 this appears to be post-link running cabal-dev itself:

$ cabal install cabal-dev --verbose=3

Could you send me (or post to hpaste) the complete output of 'cabal install cabal-dev --verbose=3' ?
