you should use dh_pythonsupport (from python-support). (or
dh_pycentral from python-central). python-support comes with a very
friendly documentation in /usr/share/doc/python-support/README.Debian to
help you through python packaging.

By removing misc:Depends, you are simply potentially shooting yourself
in the foot. Debhelper could need to add a dependency via misc:Depends
at some point in the future, and the only way you'll find out about it
is if you notice it in the changelog. If you keep misc:Depends in the
control file, debhelper will automatically do the right thing in the
future.

This is a misfeature of dpkg-gencontrol.

Is 'dh_gencontrol' not useful then? If not, why is it in the
boilerplate created by 'dh_make'? If it is useful, what am I doing
differently that it triggering its misfeatures?

Please read man dh_gencontrol... of course that it's still required. A debian package without a control file is not a Debian package. dpkg-gencontrol spits outs useless warnings but the work done is still essential to the creation of a Debian package.

That's because you're calling "dh_clean -k" which removes what has been
installed...

But there's more to clean in that package. It's arch: all and should not
be built with all python versions like you're doing. Thus there's no need
to build-depend on python-all-dev but only python-dev, etc.
There's a bashishm in debian/rules:

Strange. That's another one placed in debian/rules by 'dh_make'. Under
what circumstances would that be a good thing to do at the start of
the 'install' rule?

I've now moved 'dh_clean -k' to the end of the 'binary' rule.

That was my optimisation. Fixed now.

I admit to being confused between the recipes for building a Python
package for 'arch: any' and 'arch: all'. You're saying I need to make
this change:
-Build-Depends: python-all-dev
+Build-Depends: python-dev
What other changes do I need to make for an 'arch: all' Python
package?

Nope, dh_clean -k is fine. It's just that installation should start
after calling it, not in the build target.

Isn't that what is shown above (before the patch removes the line)?
After moving 'dh_clean -k' from the 'install' target to the 'binary'
target, the package now builds properly for me (AFAICT). Where are you
saying that line should be moved to?

Installation currently happens in "install-pythonX.Y" which is called before the
"install" target since it's a dependency. Thus dh_clean -k removes what's
installed.
Since the package is "arch: all" the python setup.py call should simply be
placed in the install target and the targets install-pythonX.Y should be
removed.
