Thank you so much for your help, now I can build both packages without hassle. The filled-in module template is dynamically computed [1], so I do not need to care about passing the version number around.

I don't think it is wise to let the user update the version number with a simple configure switch or make variable; it could make things very confusing for debugging. Updating the version number is more of a maintainer task, so it makes sense to write it in stone during the maintainer phase (bootstrap / autoreconf). divoplade
