My SourceGraph programme (available on Hackage) can do this with a few 
1) Only supports functions, not data constructors, types, etc.
2) The project must  be Cabalized
3) The functions exported must not be available from the library (though if it's
an executable, then it will return all non-called functions that aren't called

This is basically what SourceGraph does.

Note that it hasn't been upgraded to GHC-6.10 yet, nor the HSE-4 series.
