Leonard Lausen updated ARROW-10868:
-----------------------------------
    Description: 
Compiling and installing C++ library via:


{code}
cd ~/src/pyarrow/cpp
mkdir build
cd build
CC=clang-11 CXX=clang++-11 cmake -GNinja -DARROW_PYTHON=ON ..
ninja
sudo ninja install
{code}


Then installing python package as follows will claim to succeed, but actually 
fail to provide `pyarrow.lib` (`python3 -c 'import pyarrow.lib'` will fail)

{code}
cd ~/src/pyarrow/python
pip install --user .
{code}
