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

Try building with {{-Dc-ares_SOURCE=BUNDLED}}. That will force using of the static library during linking

> 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!
