SSLに対応
./counfigureの実行後、makeの前に [ Modules/Setup ]を以下のように修正します。204行目ぐらい
-- ここから
  #SSL=/usr/local/ssl
  #_ssl _ssl.c \
  #       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
  #       -L$(SSL)/lib -lssl -lcrypto
+ SSL=/usr
+ _ssl _ssl.c \
+       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
+       -L$(SSL)/lib -lssl -lcrypto
-- ここまで
$ make
$ make install
インストールしたPythonを参照するように環境変数を変更します。
$ vi ~/.bashrc
-- 追記
export PATH=/home/google/ll/py/bin:$PATH
export PYTHONPATH=/home/google/ll/py/
--
$ source ~/.bashrc
以下のような結果が出力されれば環境変数の変更ができています。
$ which python
~/ll/py/bin/python
$ python -V
