Issue

Currently on MacOS the process to install the python package is as follows.

$ brew install gcc@5
$ export CC=/path/to/gcc-5; export CXX=/path/to/g++-5; pip install xgboost

Question

What I would like to learn from a more experienced contributor is whether there are any plans to simplify this install process? The above is not tenable for an automated install system for any package that depends on xgboost. What would be required to make xgboost compatible with Apple's clang.
