Was trying to install Tweepy library for python.
Encountered below:

1) yum install python-setuptools -y [success]
2) easy_install tweepy [success]
3) Made a simple script, trying to make use of Tweepy [Failed]

so tried to easy_install simplejson, also failed:
[root@chi alakClient]# easy_install simplejson

So what was the issue? pyhton version!
sumply:

yum update python -y

and voila! \o/ Everyhting works perfectly. simplejson package was included in pyhton 2.6.
