So at least fplll is the only thing that is not found.

This check does not find the header for some reason:
checking fplll/fplll.h usability... no
checking fplll/fplll.h presence... no
checking for fplll/fplll.h... no
However the file exists in the backported libfplll-dev package. Not sure
yet what's the problem.

Forget about that. It could only happen if you build in a more manual
way (for example when following the wiki page and forgetting a step).
