Installation from Github fails on Mac

[rmendels]

Running os 10.12.6, latest Xcode, R3.4.2. This problem has arisen in other packages:

Found a solution - an R compatible version of clang with openmp included:

Yes, I just switched to Mac as well, and found out the same issue couple weeks ago. Glad you got it working.
