Yes, GNU Radio does not work with Python 3, yet. We will have to make
sure it checks that the Python version is less than 3.

I'm assuming you are running a parallel make? Try just running "make"
with no options and see if that works. This looks like a bug that
we've had for a while that only shows up on occasion and when running
large parallel makes. It generally goes away when you run make again.
We thought we had squashed this one, but it seems to becoming more of
a problem again.

In the future, you can try something like "make -j8 -k". That will
finish everything it can, even if there are errors with the doc
generation. You can then run "make" after that to capture the rest of
it.
