title: uwsgi python3 plugin doesn't work
body: <p>i compiled uwsgi with make and it's successfully done,and now i decide to run my django1.5 site with python3.3 . i've checked for the doc (<a href="http://projects.unbit.it/uwsgi/wiki/Guide4Packagers" rel="noreferrer">http://projects.unbit.it/uwsgi/wiki/Guide4Packagers</a>) and set up python3.3 development headers through apt-get and then compile the plugin by:</p>
  
  <blockquote>
    <p>python3.3 uwsgiconfig.py --plugin plugins/python package python33</p>
  </blockquote>
  
  <p>then it says:</p>
  
  <pre><code>using profile: buildconf/package.ini
  detected include path: ['/usr/lib/gcc/i686-linux-gnu/4.7/include', '/usr/local/include','/usr/lib/gcc/i686-linux-gnu/4.7/include-fixed', '/usr/include/i386-linux-gnu', '/usr/include']
  *** uWSGI building and linking plugin plugins/python ***
  [i686-linux-gnu-gcc -pthread] /usr/lib/uwsgi/python33_plugin.so
  *** python33 plugin built and available in /usr/lib/uwsgi/python33_plugin.so ***
  </code></pre>
  
  <p>it seems all is well done and i do find python33_plugin.so in that dir.
  nginx is running and is ok,now my uwsgi ini file is like this:</p>
  
  <pre><code>[uwsgi]  
  socket=0.0.0.0:8000 
  listen=20
  master=true
  pidfile=/usr/local/nginx/uwsgi.pid
  processes=2
  plugins=python33
  module=django_wsgi
  pythonpath=
  profiler=true
  memory-report=true
  enable-threads=true
  logdate=true
  limit-as=6048
  </code></pre>
  
  <p>and when i run "sudo ./uwsgi uwsgi.ini",</p>
  
  <pre><code>[uWSGI] getting INI configuration from uwsgi.ini
  open("./python33_plugin.so"): No such file or directory [core/utils.c line 3347]
  !!! UNABLE to load uWSGI plugin: ./python33_plugin.so: cannot open shared object file: No such file or directory !!!
  </code></pre>
  
  <p>it doesn't find the .so file.anyway then i copy the .so file to the uwsgi dir,and run again,</p>

  <p>i'm using ubuntu 13.04 and python2.7 and python3.3 are preinstalled. </p>
  
  <p>I SET THE PYTHON33 PLUGIN BUT UWSGI STILL LAUNCHES PYTHON2.7 ,why?</p>
  
  <p>anybody who ever met this problem? and by the way i don't like to setup uwsgi and plugins through apt-get,because it won't work at any PaaS.</p>
  
  <p>thanks!</p>
