I would recommend not using "import", which would actually install the 
module in sys.modules and possibly screw up imports of other, legitimate 
modules you have created. Also, importing from a fullpath is not very 
straightforward.

Instead, consider the config file a Python "script", not a module. Your 
program can read in the script, compile it, and execute it in namespaces 
that you define. Here's a brief example:

def load_config(filepath):
     myconfig = {}
     try:
         execfile(filepath, myconfig)
     except:
         print "config file raised an error"
         return {}
     # examine stuff in myconfig, if you want,
     # I left it out
     return myconfig
