-------------------------------------------------------
[~danrobinson010@gmail.com] Thanks for the tip.
I have tried to install the master branch code with the following steps:
{code}
[qxu@localhost dev-build]$ export ARROW_HOME=/usr/local
[qxu@localhost dev-build]$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local
[qxu@localhost dev-build]$ make
[qxu@localhost dev-build]$ sudo make install
{code}
It moves forward. Now the error message is
{code}
[qxu@localhost dev-build]$ python
Python 2.7.5 (default, Nov 20 2015, 02:00:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Where does Python looks {{libarrow.so}} for?

> Key: ARROW-66
> URL: https://issues.apache.org/jira/browse/ARROW-66
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Environment: CentOS 7.0; Python 2.7.x
> Reporter: Qian Xu
> Labels: documentation
>
> I followed [the guide|https://github.com/apache/arrow/blob/master/python/doc/INSTALL.md] to install Arrow project from scratch. I met some issues.
> 1. First of all, I need to build the cpp part. So I setup the thirdparty dependencies. But when I {{cmake -DCMAKE_INSTALL_PREFIX=$ARROW_HOME ..}}, it shows an error at {{get_filename_component}} with {{FindGTest.cmake}}. After some digging, I noticed that I have to use *cmake 3* (instead of cmake 2).
> 2. Now I am able to install {{pyarrow}}. The installation went smooth. But when I import the module {{pyarrow}}, it says {{ImportError: No module named array}}. I haven't found any description on this error.
