pipでパッケージを入れようとした際に色々苦労したのでその記録を残します。
RHEL系のOSはpipがインストールされていないので、↓のようにインストールする必要があります。
% yum install epel-release
% yum install pip
普通はyumでサクッとインストールできるはずなのに、何故か「そんなパッケージはない！」と怒られてインストールできませんでした。
yum でインストールできない場合は↓のようにrpmで入れるとよいです
% rpm -ivh http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
% pip --version
pip 7.1.0 from /usr/lib/python2.6/site-packages (python 2.6)
これでpipが入りました。
pipをインストールしてすぐにパッケージを入れようとすると↓のように怒られてしまいます。
% pip install psycopg2
You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

なので、pipをアップグレードしましょう。
% pip install --upgrade pip
pipアップグレードすると大抵はスルッとパッケージをインストールできるのですが、ものによっては下記のように怒られてしまいます。
