fail to install on macOS sierra

[yimingli]

I couldn't install the package on my mac. Some googling around suggests the problem might be that Apple's clang does not support openMP. But I'm not sure how to fix it. Thanks.

Here is the error message:

Hi, this is not a problem with gsynth, but a problem with Mac C++ compiler. Check out this page:

It worked. Thanks a lot!

For the convenience of potential readers, here is what I installed on my system (R version 3.4.1, macOS Sierra 10.12.6) to fix the problem:

1. gfortran 6.1 from https://gcc.gnu.org/wiki/GFortranBinaries#MacOS
2. clang4 R Binaries from https://github.com/coatless/r-macos-clang

[xuyiqing]

Thank you. I'll put it in the ReadMe file!

@xuyiqing update README.md to

https://github.com/coatless/r-macos-rtools

This setups the macOS toolchain, e.g. Xcode CLI, clang4, and gfortran. No terminal is required.
