Hi Ross,

The issue is with the python3 recipe. It declares RDEPENDS_python3-dev, not
DEPENDS_python3-dev.

I'm using the Python C API. So I need headers and so lib files at build
time but only so lib at runtime.

I can add python3-dev to my recipe's RDEPENDS list, but bitbake rightfully
complains about installing -dev files to the image.

I'll check today how to fix that.
