I was also not convinced but it seems the build dependencies were
properly set this time since the new package has been tested and has
python scripting support.

Right, my question was more or less in the direction of wondering what
other distros do to find Boost+Python, despite of the fact that this
particular case in Ubuntu was a packager's fault. While this issue was
being solved in Ubuntu I kindof changed my mind to think Gentoo is
doing one thing wrong, which is not providing a default python.pc for
PkgConfig which would be enough to configure Python in the
FindBoostPython.cmake script we provide. Still, I think Boost
installations are so different among distros that most of the
FindBoostPython.cmake script is pointless except for the parts that
use PkgConfig and CMake's find_package.

So, to be concrete: Our curent FindBoostPython.cmake

- Tries using PkgConfig to find Python
  - If that works, tries to find Boost Python using CMake (~20 lines)
- If that doesn't work, tries building several combinations of library
names and include dirs and tries compiling some code to test
Boost+Python installation (~80 lines)

I argue that those ~80 lines can be removed since it is very unlikely
that they will find the right configuration; and we just stick to the
PkgConfig + CMake approach.
