I built 5.11 a while back and at that time the riverbank guy only had
-dev versions of sip and PyQt5. I'll have to catch up with that and
build a proper 5.11 version.

Thanks for the patch.

I already had a build script for 5.10.1 so it wasn't really going out
of my way. I don't know if the gentoo guys have fixed this, but I had
to disable gstreamer support to get anything 5.10+ to build, but I'm
guessing gentoo has a newer version.

Personally, I'll keep updating just to stay up-to-date with the
latest qtwebengine code/fixes for qutebrowser to improve.

The one thing that worries me the most is that sip may need to be
included as a module in other python apps, and of course I've changed
the name of it to not mess with the stock sip. Therefore anyone
building anything based on that module will need to do some renaming.

I really don't know of anything else using it though, and PyQt5 was
happy with just the binary path/name and the include dir.


Shoot me again.
Just proving that the quickest way to solve the problem is to post a
whine to the newsgroups: within moments the solution presents itself to
me, and meanwhile my ass is hanging out on the Net... *sigh*...
