[CentOS] Dell openmanage srvadmin on 5.6

Hi all,
       I'm just trying to get Dell openmanage to run on my Centos 5.6
box. The monitoring
stuff appears to have installed but the web server stuff is
complaining it needs openwsman
2.2.3 or later and I can only find that for RHEL/Centos 6, not 5.

Can anyone point me at a suitable rpm, or do I have to resort to
compiling it? Surely I'm not
the only one trying to do this.
