Please don't get me wrong, I'm grateful for you advise and explanations.

It's just that I've checked behavior of Requires/PreReq a long time ago
with FC4 and am surprised to see that my assumptions are (completely)
wrong...

The original question as about creating a user/group as owner of some
files in the libs-package. The creation was done by %pre in the
base-package. Installing the -libs works, but gives errors about the
missing user/group.

A missing binary or library is obviously not the case here.

My conclusion:
	Put the creation of users/groups in the <package>-libs,
	<package> will be installed after <package>-libs.

Thanks,
Niels (who is still a bit confused)
