I suppose you have successfully repaired your car, but don't know what an
engine might be ;)

The error traceback explained: Python is trying to call a function named
_quote() in a module named pg. The most likely reason is either that you
have the wrong version of the module or a module unrelated to the required
one that has the same name and appears earlier in Python's search path.
You can start debugging with
$ python2.7 -c'import pg; print pg.__file__'
to find out the filename and then look into the corresponding .py file.
If that is related to postgresql you are probably seeing a version mismatch.
Consult PyKota's documentation to find out the program's dependencies.
