Can't install pyhsmm on macOS 10.14.5

Hi all,

I am having some trouble when installing the pyhsmm library. I follow the instructions of the readme file and when I do python setup.py install I get:

running install

I'm using macOS Mojave (version 10.14.5) with python 3.7 and clang:

Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.6.0
Thread model: posix

Any idea of what is going wrong? Any help would be much appreciated.
