[CentOS] Centos 3 - yum update error (rpm-libs)

[Maciej Żenczykowski]

> Package rpm-libs needs rpm = 4.2.3-13.WB2, this is not available.

do "rpm -qa | grep ^rpm"
see what rpm-related packages you have installed and redownload
them and instal them from centos3.

possibly also run "rpm -qa | grep -i WB" and reinstall all WB specific 
packages to (hopefully) get rid of such problems in the future...

Cheers,
