It seems that the problem is that timestamp on the libtool.m4 file is
too old. My guess is that in MET, the timestamp somehow underflows. By
setting the timestamp to 1980 (instead of 1970) the problem disappears,
at least on my machine.

In clean pbuilder environments, you probably do not have the timezone
set, so the 1970 timestamp does not underflow...

Attached patch fixes the problem for me. Mario, Simon, can you confirm?
