snakebacon v0.0.1 compiles but doesn't properly install on MacOSX

[brews]

snakebacon v0.0.1 compiles but doesn't properly install on MacOSX.

First, I downloaded source from the release. Created test_env in Conda and activate it. Run:

python setup.py build_ext --inplace
to compile cython and C/C++.

I then ran unittests on the locally-compiled code and everything seemed fine.

Local package install with:

python setup.py install --user
switched to a clean directory and tested the installed package in ipython. Got the error on import.

Here is the error in an ipython session:

The key here seems to be Library not loaded: @rpath/libgsl.19.dylib. Looks like it is having trouble with GSL when installed from Conda.

[brews]

Install seems to work if we use the conda-forge channel when creating our virtual environment.

I think we can add this to our testing environments. Sounds like it might be trickier when building the actual package. See: conda/conda#988 and conda/conda-build#532.
