Hmmm, what does `/usr/bin/env python3` return?
I have fixed a bug usptream: lvmdbusd must use python 3 interpreter
detected by configure script not the python3 found in $PATH.

That's true, it is not. It is python3 only.

It says "python bindings". It is those python2 and python3 bindings we
plan to remove in future - it never worked really well, had problems
with configuration - and lvmdbusd is the intended replacement.
D-Bus daemon is written in python(3). And it should not require python
bindings (and actually neither the applib - I fixed that bogus error
upstream.)
It may see and rewrite to a compiled language, if that happened to be a
bottleneck.

It should not be.
