Hi Maintainer

The yade package has a build-dependency on python3-all-dev, but its
debian/rules only builds for one python3 version.  This causes issues
for tracking transitions, since packages build-depending on
python3-all-dev are expected to build for all supported python3
versions.

The package should either build-depend only on python3-dev, or it
should build for all supported python3 versions.

Regards
Graham
