OK, No, I do not think it is necessary. Removed.

I ran into some initial problems with the 0.10.3 version due to my
limited understanding of the python build system.  I then compared to
0.10.2 which made me aware of some errors.  So I ended up with
definitions for both versions.

I do not use this library myself.  I write mostly python-3 code myself,
so I would have liked a python-3 version of rope.  It seems that elpy is
focusing more on jedi for python-3, so I will probably look at that.
If nobody else is interested in a rope_py3k package then let's just drop
it.

It does indeed not run on python-3.  About 57 test fail with python-3.

I agree. Done.

Indeed.  I did not notice that before.

I expanded it a bit.  I am not exactly sure what to write as I am not
very familiar with the project.  Hope this will make it more clear. 

An updated patch is attached.
Thank you for your review!

Best,
