My POV is wrong :( (see below)

You are close here - but I still disagree slightly. As I understand things,
the problem is the incompatibility between the upstream code (above) and the
Debian version - 1.49.0 vs 1.49.0.1.

"but this is forgotten later". Take it as nitpicking - there is a difference
between "not used" and "forgotten". But the *effect* is the same - FTBFS.
