Warning: You are using OS X 10.11.
We do not provide support for this pre-release version.
You may encounter build failures or other breakage.
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

I suspect it's trying to find /Applications/Xcode.app/ rather than /Applications/Xcode-beta.app/. If you symlink the latter to the former, does compile work?

[jamieshorten]

That sorted it.

Thanks
