[Samba] Installation SerNet Samba Build Key 1.0.2 failed

[Walter Neu]

As the SerNet Samba Build key will expire soon, I wanted to install the
new key with the extended validity:

http://ftp.sernet.de/pub/sernet-build-key-1.0-2.noarch.rpm

But the installation on a CentOS 5.3 failed with dependencies:


Fehler: Fehlgeschlagende Abhängigkeiten:
        rpmlib(PayloadIsLzma) <= 4.4.6-1 wird benötigt von
sernet-build-key-1.0-2.noarch


Any suggestions??
