----------------------------------

             Summary: pyarrow 0.4.0 on pypi is missing pxd files
                 Key: ARROW-1086
                 URL: https://issues.apache.org/jira/browse/ARROW-1086
             Project: Apache Arrow
          Issue Type: Bug
            Reporter: Jacob Scott


{{pip install pyarrow==0.4.0}} does not install the pxd files found in 
{{python/pyarrow/includes}}. 

This prevents use of pyarrow Cython code downstream; something as simple as 
{{from pyarrow.lib cimport Array}} fails due to

{code}
/Users/jhscott/.virtualenvs/arrow_cython/lib/python2.7/site-packages/pyarrow/lib.pxd:
 cannot find cimported module 'pyarrow.includes.libarrow'
/Users/jhscott/.virtualenvs/arrow_cython/lib/python2.7/site-packages/pyarrow/lib.pxd:
 cannot find cimported module 'pyarrow.includes.common'
{code}

Manually copying these pxd files from the arrow source tree into the location 
Cython complains about fixes the problem.

See https://github.com/snakescott/arrow_cython for an example repro.
