...and that said, Requires(posttrans) is now implemented in 
rpm-4.9.0-0.beta1.4.fc15 and can be used once the new version hits the 
builders (in an hour or so). Unlike some other qualifiers that have been 
used while rpm was looking the other way, posttrans reflects an existing 
mechanism and expecting Requires(posttrans) to work is perfectly 
reasonable (pretrans dependencies were already implemented in 
rpm-4.9.0-beta1)
