While we're talking about RPM dependencies ...

[Richard W.M. Jones]

Today when using F17 Alpha, I ran qemu and got an error which was
something like:

  qemu-kvm: undefined symbol usbredirhost_foo

(I don't recall the precise symbol).  This was just because that
version of qemu was compiled against a later version of
libusbredirhost.so (but one with the same soname), and updating
libusbredirhost.so fixed the problem.

The 'qemu' package has a bug, of sorts: the maintainer should have
added a specific Requires line:

  Requires: usbredir >= <some version>

However, instead of pushing this problem on packagers, maybe RPM
should resolve this by encoding the (admittedly long) list of symbols
used by a binary?

Rich.
