导入PyV8时权限被拒绝

Question

>>> import PyV8
Traceback (most recent call last):

        stream = open(path, 'rb')
    IOError: [Errno 13] Permission denied:  
        '/usr/local/lib/python2.7/dist-packages/google_apputils-0.4.2-py2.7.egg/EGG-INFO/namespace_packages.txt'

I had some problem while installing PyV8 as mentioned here - error: command 'c++' failed with exit status 1 but solved that using http://ubuntuforums.org/showthread.php?t=1480282#post_11247864 . But now when I import, it says Permission Denied.

/usr/local/lib/python2.7/dist-packages/google_apputils-0.4.2-py2.7.egg/EGG-INFO/namespace_packages.txt的权限是什么？
