Hmm... Judging by the traceback you pasted, ihooks.py is doing what it's 
supposed to...

Bio/__init__.py is trying to execute:
     config_imports = __import__("Bio.config", {}, {}, ["Bio"])

Which is equivalent to:
     from Bio.config import Bio

And that's equivalent to:
     import Bio.config.Bio
     Bio = Bio.config.Bio

So, if the code in __init__.py is correct, the module "Bio.config.Bio" 
should exist.

Load up a python interpreter (or whatever environment can load the Bio 
module properly), import Bio as you normally would when using it in your 
program, and then check if the Bio.config.Bio module exists. Maybe 
there's something sneaky going on inside Bio where it's creating that 
symbol at runtime, and ihooks isn't finding it because it's looking at 
the filesystem to resolve module names.
