Pillow doesn't install in my virtualenv environment
<p>My issue is when I enter on my environment and then try to install <strong>Pillow</strong>, it doesn't install on my environment (<em>this is not a problem of dependencies like libjpeg8-dev and others package</em>s). However, if I try to install another library, e.g. <strong>geopy</strong>, it works. Kinda rare behavior.
I looked at my list of libraries with <strong>pip list</strong> and still I've never seen <strong>Pillow</strong> installed on my <strong>venv</strong>.
I'm running my application in a Centos 7.1 x64 machine.
I'm using Python 3.4.3, virtualenv 12.0.7, pip 8.0.0 and setuptools 12.0.5.
Oh, before I forget it. Other library that doesn't appear in my venv is psycopg2.</p>

<p>Please help, this is such a headache. I don't have any traceback to show you guys, because everything seems to work "normally".</p>
