Wes McKinney commented on ARROW-2326:
-------------------------------------
Here's what otool shows for libarrow.dylib:
{code}
$ otool -L
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pyarrow/libarrow.10.dylib
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pyarrow/libarrow.10.dylib:
@rpath/libarrow.10.dylib (compatibility version 10.0.0, current version
10.0.0)
@rpath/libarrow_boost_system.dylib (compatibility version 0.0.0,
current version 0.0.0)
@rpath/libarrow_boost_filesystem.dylib (compatibility version 0.0.0,
current version 0.0.0)
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current

{code}
If I load the shared libraries manually things do work
{code}

>>> import pyarrow
WORKS
{code}
I suspect we need to use {{install_name_tool}} to "fix" these shared libraries.

> I dug into it a bit and found that in older versions of install.rst, Wes

> going on here for me. I'm on 10.9, I know it's really old, so if these wheels
> can't be made to run on my ancient OS, I just wanted to report this so the
> wheels uploaded to PyPI can reflect this incompatibility, if that is indeed
> the case. I might also try some otool / install_name_tool tomfoolery to see
> if I can get a workaround for myself.
> Thank you!
