title: calling third party c functions from python
body: <p>I have a requirement of calling third party c functions from inside python.
  To do this I created a c api which has all the python specific c code ( using METH_VARARGS) to call the third party functions. I linked this code liba.so with the 3 party library libb.so
  In my python file , I'm doing:</p>
  
  <pre><code>import liba *
  </code></pre>
  
  <p>Python now complains libb.so not found.
  What am I doing wrong ?</p>
