Description

The pyarrow package lists numpy >= 1.9 as a dependency in setup.py - however, it causes an exception at import time with numpy 1.9.

Repro steps:

{{$ pip install numpy==1.9
...
$ pip install pyarrow
...
$ python -c 'import pyarrow'
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/dima/envs/pyarrow-bug/lib/python2.7/site-packages/pyarrow/_init_.py", line 28, in <module>

}}

(Additionally, requirements.txt lists "numpy>=1.7" - though it doesn't look like it's used at all.)
