Python SDK import エラー "dynamic module not initialized properly"

ソフトバンクの公式サイトからインストールしたPython SDKのモジュールをインポートしたいのですがこのようなエラーが出てしましいます。

>>>import naoqi

SystemError: dynamic module not initialized properly

「動的モジュールが正しく初期化されていません」とのことなのですがどうすれば良いのかわかりません。
ちなみに、~/.bash_profileのPATHこのように通しています。

# Naoqi Python SDK PATH
PYTHONPATH=${PYTHONPATH}:/Users/"user_name"/Documents/pynaoqi-python2.7-2.5.5.5-mac64/lib/python2.7/site-packages
export PYTHONPATH
DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:/Users/"user_name"/Documents/pynaoqi-python2.7-2.5.5.5-mac64/lib
export DYLD_LIBRARY_PATH

環境はMacOSです。
