1) pip install pyarrow==0.14.0
2) All the pyarrow files including, for example libarrow.so.14, but not
libarrow.so (hence the linker error)
Reproducible on Python 3.7.2 on linux mint 19.1 and debian docker:
Example dockerfile:
```
FROM debian:unstable-slim
RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y python3 python3-dev
RUN apt-get install -y python3-pip
RUN python3 -m pip install --upgrade pip
RUN pip3 install Cython pyarrow
COPY setup.py /root
COPY test.pyx /root
WORKDIR /root
RUN python3 setup.py build_ext --inplace
```
Where setup.py and test.pyx are the files listed above, with an added call
to numpy.get_include().
Appending ' ==0.13.0' to the 'RUN pip3 install...' line above results in
the docker image building
