You will want to ask IPython questions on the IPython mailing list:

   http://mail.scipy.org/mailman/listinfo/ipython-user

The reason you do not get the source is because there is no file that contains 
functions defined in the interactive interpreter. %psource uses the inspect 
module, and the inspect module explicitly only looks in real files using the 
linecache module. IPython could be modified to inject fake files into the 
linecache, but that's a chunk of work. I am sure they would be happy to 
incorporate a patch if you were to provide it to them.
