opensslが古いとpythonのいろんなところに問題が出る

この問題で3時間が消失しました．

一番の問題

easy_installが必要なパッケージを見つけてくれません．pipも同様です．

# easy_install pip
Reading https://pypi.python.org/simple/pip/
Download error on https://pypi.python.org/simple/pip/: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed -- Some packages may not be found!

yumすれば良いのに

yum install openssl-devel をすれば良いのでは，と思うかもしれませんが，root権限がない一般人にはできません．:p

差し当たりどうするか

まずはpipのtar.gzを入手して，インストールします．

# wget https://pypi.python.org/packages/source/p/pip/pip-6.0.6.tar.gz --check-no-certificate
# tar xzvf pip-6.0.6.tar.gz
# cd pip-6.0.6.tar.gz
# python setup.py build
# python setup.py install

このままだと，古いOpenSSLのせいで，pipがSSLの検証に失敗するので，pipを改造します．
（参考： docs/TSUBAME http://www.kyogoku.biz/docs/TSUBAME)

# vim ~/src/downloads/python-2.7.6rc1/lib/python2.7/site-packages/pip-6.0.6-py2.7.egg/pip/downloads.py
Dispatch the actual request と書いてある行の次を，
return super(PipSession, self).request(method, url, verify=False, *args, **kwargs)
と書き換える。(verify=False を書き足す．) 

これでさしあたりの問題は解決したはず．
