I think ghci is just not smart enough to know that it should change to the parent directory and run it from there. As such, it's trying to find "A.B.C" from the context of the current directory, and the file is not in A/A/B/C.hs so it can't find it.

So it's just a limitation of ghci (I think).

http://hackage.haskell.org/trac/ghc/ticket/3140 is almost exactly the same thing.
