Wes McKinney commented on ARROW-5751:
-------------------------------------

I confirmed the problem

{code}
$ otool -L /Users/wesm/miniconda/envs/wheel-test-3.7/lib/python3.7/site-packages/pyarrow/libarrow_flight.14.dylib 
/Users/wesm/miniconda/envs/wheel-test-3.7/lib/python3.7/site-packages/pyarrow/libarrow_flight.14.dylib:
	@rpath/libarrow_flight.14.dylib (compatibility version 14.0.0, current version 14.0.0)
	@rpath/libarrow.14.dylib (compatibility version 14.0.0, current version 14.0.0)
	/usr/local/opt/c-ares/lib/libcares.2.dylib (compatibility version 6.0.0, current version 6.0.0)
	/usr/local/opt/openssl/lib/libssl.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.5.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.50.2)
{code}

This can be easily confirmed by installing the wheel from https://github.com/ursa-labs/crossbow/releases/tag/nightly-489-travis-wheel-osx-cp37m

I'll work on a patch

> I'm afraid while [https://github.com/apache/arrow/pull/4685] fixed the macOS wheels for python 3, but the python 2.7 wheel is still broken (with a different error):
> {code:java}
> ImportError: dlopen(/Users/pcmoritz/anaconda3/lib/python3.6/site-packages/pyarrow/lib.cpython-36m-darwin.so, 2): Library not loaded: /usr/local/opt/c-ares/lib/libcares.2.dylib
>   Referenced from: /Users/pcmoritz/anaconda3/lib/python3.6/site-packages/pyarrow/libarrow_python.14.dylib
>   Reason: image not found{code}
> I tried the same hack as in [https://github.com/apache/arrow/pull/4685] for libcares but it doesn't work (removing the .dylib fails one of the earlier build steps). I think the only way to go forward on this is to compile grpc ourselves. My attempt to do this in [https://github.com/apache/arrow/compare/master...pcmoritz:mac-wheels-py2] fails because OpenSSL is not found even though I'm specifying the OPENSSL_ROOT_DIR (see [https://travis-ci.org/pcmoritz/crossbow/builds/550603543]). Let me know if you have any ideas how to fix this!
