錯誤安裝Python包裝的openkinect

Question

我試圖在Ubuntu 12.04的OpenKinect安裝Python包裝，但我不能因爲這個錯誤：

$ sudo apt-get install python2.7-dev 
python2.7-dev : Depends: libexpat1-dev but it is not going to be installed 
       Depends: libssl-dev but it is not going to be installed 
E: Unable to correct problems, you have held broken packages. 

Python包裝需要這些依賴關係：

1. 用Cython
2. 蟒-dev的（上述錯誤）
3. 蟒-numpy的

我已閱讀該post，但它不適用於我

我該如何安裝python-dev？
