Policy question re: Haskell Platform installer on OSX

Hi all, I'm currently writing a program to take Cabal libraries and turn them into OSX .pkg files, for the Haskell platform's Mac installer. Where should the libraries be installed? The current GHC installer plops them down into /Library/Frameworks/GHC.framework/Versions/xxx/usr, and my thinking is that I'll keep it that way so that we can piggyback on GHC's uninstall script. Otherwise the platform project will need an uninstaller of its own. Thanks, G. -- Gregory Collins
