This is due to a bug in waf that was fixed about a year ago.

Can you update to the latest version of waf so tut can be built with the latest version of python?

[mrzechonek]

Sure, I'll try - hopefully waf didn't change the API again ;)

[adamjstewart]

@mrzechonek any updates on this? Python 3.8 is now out as well.

[adamjstewart]

@mrzechonek any updates? Python 3.9 is now out, and 3.10 is around the corner...

[mrzechonek]

My 2nd kid is also out (-;

[adamjstewart]

3.10 is now out...

[mrzechonek]

Well, at this point all I can say is that I'm happy to accept a PR. Sorry, life happens.
