Which system is this on?   GNU/Linux x86_64?
$ grep "^deplibs_check_method" ./libtool

is pass_all, right?

By fighting a long and hard fight on one of the Libtool lists to kill
pass_all on your system: it's wrong there.  I'm on your side, BTW.  ;-)
(And there is a TODO item for this, too.)

It was changed to pass_all because of times the previous setting did the
wrong thing for many people, or so I think (was before my time).
