title: Install pip on pypy
body: <p>I want to speed up my program so i'm trying to setup pypy + psycopg2cffi.
  This program opens a xml, parses it and then insert some data in a database.
  I'm using currently python3, postgresql and psycopg2 but this approaches is really slow.
  So i want to try run my program with pypy + psycopg2cffi.
  I have python 3 and pypy, and i want to install psycopg2cffi so i ran this command:</p>
  
  <pre><code>pip install psycopg2cffi psycopg2cffi-compat 
  </code></pre>
  
  <p>But psycopg2cffi was only installed on python because when i try to import psycopg2cffi on pypy this is the error i get:</p>
  
  <pre><code>ImportError: No module named psycopg2cffi
  </code></pre>
  
  <p>So i think i need to install pip first but i can figure out how to do this.</p>
  
  <p>How can i install it on pypy?
  Thank you.</p>
