pow is nothing unusual and really should be in libm. The only thing I
could imagine is that libm isn't linked for some reason or the order
of libs is wrong (?). Can you show the error mesaage and the line
containing the compiler call? Does it happen with special frontends
only (e.g. only scanimage but not xscanimage/xsane)?

What does "sane-config --libs" return?

Does this occur when you actually run the frontend?

As I said I'm surprised that dynamic linking works at all. It doesn't
do on my NetBSD installation.

I don't know. I have never seen similar things on any platform
(including NetBSD). As this isn't the only problem you observed with
SANE: Are you really sure that there aren't some major problems with
you installation of NetBSD?

Bye,
