Library not loaded: @rpath/libz.1.dylib

I am getting this error
```

OSError: dlopen(/Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib, 6): Library not loaded: @rpath/libz.1.dylib
Referenced from: /Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib
Reason: image not found
```

python path
/usr/bin/python

pip path
/usr/local/bin/pip

Start by reproducing the import failure with /usr/bin/python and the installation from /usr/local/bin/pip. Inspect how /Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib resolves @rpath/libz.1.dylib; done means the llvmlite binding loads successfully in the reported environment.
