Also, the Haskell Platform ./configure step checks which version of GHC you have installed, and requires you to pass the option --enable-unsupported-ghc-version in order to compile it with anything other than GHC 7.4.2.

Did you try an unsupported version? And now you're complaining?

This is getting into minutia now, but yes I tried the unsupported flag and as I already explained it barfed about the prelude.

How is it minutia that you expect an unsupported version of GHC to work?

Yes, I try it out sometimes. And if it works, great. If not, too bad, I'll wait until the next Haskell Platform. I don't whine about it in public.

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.

So the complaint is about Ubuntu?

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.

That's not a very good point. It sounds as though you're the one who moved furniture around, considering that you managed to mix up Ubuntu's GHC package with your hand-built ones.
