This is getting into minutia now, but yes I tried the unsupported flag and as I already explained it barfed about the prelude. So I installed 7.4.2 from source but that confused cabal because my attempt to uninstall the ubuntu package with 7.4.1 in had failed with dependency-hell. Figuring out why (or even that) my packages weren't being seen was the puzzle I was referring to. The point is that we wouldn't have to be talking about this at all if people didn't move the furniture around all the time. > Likewise, the strong type system and the often helpful type error messages > make it really easy to update code to work with more modern libs! I'm also a big fan of the error messages, but it's nice to know if I caused them or somebody else did.
