[Haskell-cafe] cabal-dev add-source

[JP Moresmau]

That's exactly what I'm doing, and I was exactly following these notes, but
it doesn't work. This google+ post and the answers to it (
https://plus.google.com/102016502921512042165/posts/TGaENqWfubP) lead me to
at least one solution that seems to work: you need to unregister the
changed package first.
So
cabal-dev ghc-pkg unregister --force P1
cabal-dev add-source ../P1
cabal-dev install

Does the trick. There seems to be a way to pass a --reinstall flag to
cabal-dev install but I haven't gotten it to work yet.

Thanks

JP
