やったこと

python環境をタイトルのとおり構築。

環境

windows 7
vagrantで構築したvm
pythonはpyenvをつかってインストールなので詳細は割愛

※pyenvでのインスト－ルはこちらの通り
※上記までは完了している前提

pandasインストール

$ pip install pandas

matplotlib（可視化ライブラリ）

$ pip install matplotlib

                     numpy: yes [version 1.9.3]
                       six: yes [using six version 1.9.0]
                  dateutil: yes [using dateutil version 2.4.2]

                 pyparsing: yes [using pyparsing version 2.0.3]
                     pycxx: yes [Official versions of PyCXX are not compatible
                            with matplotlib on Python 3.x, since they lack
                            support for the buffer object.  Using local copy]
                    libagg: yes [pkg-config information for 'libagg' could not
                            be found. Using local copy.]

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ms7vpmo7/matplotlib

と、エラー・・・
上記を見る限り、pycxx、libaggのとこで互換性がないなど言われている・・・

が、トライ&エラーを繰り返し、調べ・・・て調べた結果。。。上記が原因ではなく、

Building Matplotlib requires libpng (and freetype, as well) which isn't a python library, so pip doesn't handle installing it (or freetype).
You'll need to install something along the lines of libpng-devel and freetype-devel (or whatever the equivalent is for your OS).
とのことで、pipではなく、yumで下記の通りインストール。

$ sudo yum install -y freetype*
$ sudo yum install -y libpng-devel
$ pip install matplotlib
