I notice that the OS X version is still installing binaries in /usr/bin.
If I have understood correctly, in the upcoming OS X 10.11 /usr/bin and various other directories will be locked down hard, and no third party software will be allowed there.
So perhaps the installer should be changed to install the binaries elsewhere, such as /usr/local/bin?

Mostly correct. I would argue against /usr/local though because Homebrew uses it and I'd want to avoid possible collisions, especially if someone were to e.g. install git-annex or pandoc via HB without realizing they're written in Haskell. (Yes, this happens!)

Many third party packages already use /opt, e.g. /opt/haskell or /opt/haskell-platform. (See for example XQuartz or calibre.)
