第一次执行安装的时候报错，权限不够
[monogdb@localhost pymongo-1.9]$ python setup.py install
running install
error: can't create or remove files in install directory
The following error occurred while trying to add or remove files in the
installation directory:
[Errno 13] Permission denied: '/usr/lib64/python2.4/site-packages/test-easy-install-11661.write-test'
The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/usr/lib64/python2.4/site-packages/
Perhaps your account does not have write access to this directory? If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account. If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.
以root权限给monogdb赋予访问/usr/lib64/python2.4/site-packages/的权限：
[root@localhost ~]#chown monogdb:monogdb /usr/lib64/python2.4/site-packages/
再次安装。。
