Integrate with formulas depending on the non-native gtk packages

[NikolausDemmel]

I was stumbling onto your repository while searching for a way to use native gtk with various homebrew installed gtk applications. First off, thanks for putting this up.

The problem with your formulae is that many other formulae depend on the gtk+ non-native variants in the default homebrew repo. Can you see a way to integrate your native variants with those dependet packages? Have you attempted to get your formulae merged into homebrew?

I don't know of a good way to have native GTK install easily with anything already in brew.

It would be great if homebrew could take a library that conflicts_with another library, and use that as an alternate dependency if it is installed.

It might also be better if all homebrew-native's packages were installed as keg_only and then maybe added a option in the install script to install using that keg instead.

Also I haven't looked into trying to get homebrew-native merged into homebrew because it doesn't yet meet their guidelines (I still need to write tests for the install scripts, and clean up the scripts)
