title: Unable to import SimPy
body: <p>I am new to SimPy I used the easy_install to install SimPy module then on the command line I simply tried <code>from SimPy.Simulation import  *</code> but I get the following error</p>

  &gt;&gt;&gt; from SymPy.Simulation import *
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named SymPy.Simulation
  </code></pre>
  
  <p>I use easy_install to install packages, I have simplejson install without any problem and when I import simplejson I don't get the above error. I did an update and easy_install successfully updated the SymPy module yet I still cant import the SimPy Module </p>

  Best match: SimPy 2.2

  <p>I also check the <code>easy-install.pth</code> file, and looks like everything has been added properly.</p>
  
  <pre><code>[/Library/Python/2.6/site-packages]$more easy-install.pth 
  import sys; sys.__plen = len(sys.path)
  ./simplejson-2.1.3-py2.6.egg
  ./SimPy-2.2-py2.6.egg
  import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

  <p>It will be great if I could get any help on this. </p>
