makedirs OSError [Errno 20] Not a directory 'ansible/lib'

Issue

• To create virtual environments, one use the virtualenv command. Create an environment called "testredhat" successfully.

[root@test ~]# virtualenv testredhat
New python executable in testredhat/bin/python
Installing Setuptools..............................................................................................................................................................................................................................done.
Installing Pip.....................................................................................................................................................................................................................................................................................................................................done.
[root@test ~]# cd testredhat/
[root@test testredhat]# ls
bin  include  lib  lib64
[root@test testredhat]# 

• However if one create a file with similar environment name then it throws an error.

[root@test ~]# 
[root@test ~]# touch ansible
[root@test ~]# rpm -qa | grep python-libs
python-libs-2.7.5-34.el7.x86_64
[root@test ~]# virtualenv ansible
