Since you are using i2c-tools package itself, an option should be
added to this package to build and install the python bindings. I was
going to attempt to try to explain the way to do this but it turned
out that it was completely different than what is proposed here. I
will be pushing this out here shortly and would appreciate if you
could test this new patch out.
