I looked in the site package before but can't see anything ..
(C:\Python25\Lib\site-packages\scipy\integrate)
All tests from the tests folder work, but 
I don't understand how the odepack links to the odeint (albeit i see the def...). And can't find any file lsoda.py (or .f)

I probably missed something...?

You can view the source code for lsoda on netlib. The extensive
comments at the head of the source file are clear and complete. Odeint
is just a wrapper for lsoda, so when you understand what lsoda is doing
you will be all set.

In your case, you might simply be computing for to coarse a mesh in t,
so "too much work" has to be done for each step. The error message
tells you what value of t was reached before lsoda gave up.
