I think that the path of least resistance is to make your analysis
tool command-line compatible with ghc. Then you can use it like this:
$ cabal configure --with-compiler=/path/to/my-ghc
$ cabal build
Since 'cabal build' usually just calls 'ghc --make Main.hs', you'll
need to do dependency chasing, but this can be implemented by parsing
the output of 'ghc -M'.
