rpm and dependencies.

[Erik P. Olsen]

I am trying to install next level of sane backends but it fails due to
dependencies problems. When I do:

rpm -Uvh sane-backends-1.0.13-2.athlon.rpm

I get:

warning: sane-backends-1.0.13-2.athlon.rpm: V3 DSA signature: NOKEY, key
ID e01260f1
error: Failed dependencies:
        sane-backends = 1.0.12 is needed by (installed)
sane-backends-devel-1.0.12-4

What can I do about that and why does it need something which *is*
installed??
