What you want is this:

git clone --depth=1 -b develop https://github.com/boostorg/boost.git
cd boost
git submodule update --init libs/config
git submodule update --init tools/build
git submodule update --init libs/python
./bootstrap.sh
cd libs/python
../../b2 test include=include

This works for me on CentOS 7, using the glorious preinstalled Boost 1.53. 
Two tests fail, exec and import_. (And on second thought, it should work 
even without include=include, and it does.)

For Travis, replace the `git submodule update --init libs/python` with a 
copy of the already checked out repo, as I do in the file referenced above.

Unless you hit the CI job limit, I'd still recommend the depinst-based one 
though.
