Gym: Build error by running "pip install -e .[all]"

[lbbc1117]

I got some error msg like:
Failed building wheel for pachi-py
and
ld: targeted OS version does not support use of thread local variables in _fast_srandom for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command 'g++' failed with exit status 1

I do have cmake installed:
cmake version 3.5.1

pip version is 8.0.2

OS version is Mac OS X 10.9.5

It turns out swig was missed.
After running brew install swig, every thing works.

Cool!
