I think I managed to do all the Python 3 conversions but couldn't get linking to work.
I recall that getting the prerequisites built was a challenge and found that if I changed anything in any of them I'd have to go back and start building them from scratch again. Worse, I seem to recall that for at least one of them, probably langkit, I'd have to delete it and reload it from its archive file.
Its comforting to find that many of the opinions expressed in this thread are similar to my own.
