Virtualenv in Mac OSX -bash: command not found issue

问题

I'm having a really hard time trying to use virtualenv on Mac OSX Mountain Lion.

I installed XCode, python2.7 with Homebrew and virtualenv + virtualenvwrapper using sudo PIP.

I've added usr/local/share/python to my $PATH and also followed the advice given on this site:

http://hackercodex.com/guide/python-virtualenv-on-mac-osx-mountain-lion-10.8/

and edited my ~/bashrc accordingly.

But when I run virtualenv ENV I get:

-bash: virtualenv: command not found

I've been through steps outlined in a lot of similar questions on SO but none of them have worked so far. I'd be massively grateful for some help and advice.
