Where do the "sensors" program come from? Debian package?
Hand-compiled? Which version ("sensors -v")?

Note that no hardware monitoring chip was detected on your system, so
if that's what you are after, fixing the problem above won't help you
much. Either your system has no hardware monitoring chip, or
sensors-detect failed to detect it for some reason. The complete output
of "sensors-detect" may let us help you in the second case.
