title: install scipy using pip in virtualenv on ubuntu 12.04
body: <p>I want to install scipy within the virtualenv on ubuntu 12.04. Since it is installed in virtualenv, I have to use <code>pip</code>, <code>apt-get</code> doesn't work. I have read the thread <a href="https://stackoverflow.com/questions/2213551/installing-scipy-with-pip">Installing SciPy with pip</a>, but the answer dosen't work now. If I run "pip install svn+<a href="http://svn.scipy.org/svn/scipy/trunk/#egg=scipy" rel="nofollow noreferrer">http://svn.scipy.org/svn/scipy/trunk/#egg=scipy</a>" or "pip install git+<a href="http://github.com/scipy/scipy/" rel="nofollow noreferrer">http://github.com/scipy/scipy/</a>", both error. Could you please give me a list of workable step-by-step command lines that can install scipy within the virtualenv on ubuntu 12.04 (any dependancy is included because I didn't install numpy (I don't know how))? Thank you.</p>
  
  <p>Forget one thing: I'm using python3 in the virtualenv. The installed scipy should be able to imported.</p>
