the new createrepo 0.4.3 introduces a new 'feature' that it will cache 
previous metadata for pkgs that have not changed - so that it saves time 
rebuilding the md for a repo when you have a large number of pkgs, but 
only a few have changed.

to recreate :

use createrepo-0.4.3
and "createrepo <dir to repo>"
proceed to change a few pkgs and rerun.

What I am guessing is that something on those pkgs is changing  eg. a 
resign or something - that causes the checksum to change - but does not 
hit the radar of createrepo  - perhaps createrepo is only checking for a 
rpm param like buid time or something... not sure, worth a peek in the 
code to verify. so while the checksum has changed, createrepo does not 
regen md for that package.
