title: CANNOT Install external modules in Canopy
body: <p>I have set Canopy as my default python compiler.
  I want to install scikits modules, currently not available in Canopy Package manager. I have installed setup tools and easy_install, pip which points to Canopy installation ( which easy_install -> Canopy directory). But I cannot use either of them to download any of the above modules. 
  More specifically fetching scikits.odes gives me this error log:</p>

  <p>Similar error logs were thrown for the other module installation attempts I had made.
  Any suggestions? How can I fix this obvious bug?</p>
