I tried to switch to qwt6. So, I cant find python-qwt6 in the repos
(this is for some of the grc qt widgets). So I guess that is a minor

And I got this compilation error. Any idea?

Yeah, I know exactly what the problem is. I just found it myself. It arose after I fixed some edits to be compatible with 5.2, but didn't do it right to keep it working with qwt 6. I must not have properly updated my 11.10 box afterwards to check it.

I just pushed what I believe are fixes to maint/master/next. Let me know if anyone has problems with either Qwt versions 5.2 or 6.0. 

The push to next also includes a bunch of updates to gr-digital where I've moved all of the OFDM work into gr-digital and reworked all of the examples to use UHD. Again, let me know if people experience more than the usual issues :)
