LinuxQuestions.org - [SOLVED] easy_install python-ldap Error

Hello,
I am trying to install python-ldap using easy_install.
OS is RHEL 5.6. I need to use python 2.6, so I installed python 2.6 in /usr/local/bin.
Then I installed easy install with /usr/local/bin/python ez_setup.py.
So far so good.
But when I entered "easy_install python-ldap", I got the following error.
I did some search, but could not make it work, so I am here.
Please point me to a right direction.
Thanks.

Code:

[root@localhost ~]# easy_install python-ldap
