I am struggling with a hopefully simple problem in ipython .0.8.4.  Basically, I'm finding that I need to exit the interpreter when i add a new module to site-packages.  I've tried reload et al, but these do not seem to have the effect i want, ( that effect being that i can stay in the interpreter, adding new modules to the python path , and having them available to me ) 

for example:  I have a machine:

I run ipython and try:

import django 

This does not work because I've forgotten to actually install it.

I screen over to my admin screen, install the module and then in order to get ipython to re-read the modules, I'm forced to exit and enter ipython again.  Since I run ipython out of my .screenrc this is a bit inconvenient.  How can i avoid this?
