Ah, that explains it perfectly, thanks!  The exact scenario here is that
I'm building udev/kmod in a chroot environment from a Fedora 16 host.
Fedora is running a kernel with a module directory
of /lib/modules/3.1.9-1.fc16.x86_64 but my chroot environment
contains /lib/modules/3.2.1.  So, while both the host and my chroot
environment contain all 3 .bin files in their respective modules
directories, because those directories are between the 2 environments, I
see the message above.  As it doesn't appear to have any impact on the
functionality I'm after here, I'm happy enough to leave it as-is.  I'm
guessing though, that a symlink with the same name as the host's module
directory to the chroot environment directory would work around the
issue.

Matt.
