[Spacewalk-list] spacewalk install on centos 5.4

[lee]

hi all...

trying to do a yum install spacewalk-oracle.

oracle has been installed and running....

im following this howto: 
https://fedorahosted.org/spacewalk/wiki/HowToInstall

when I do an yum install spacewalk-oracle I get this dep error:
---> Package spacewalk-backend.noarch 0:0.7.18-1.el5 set to be updated
--> Processing Dependency: rhnlib >= 1.8 for package: spacewalk-backend

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.


Now I dont want to do something here that will break the howto. It needs 
to be simpel.... plus I cant find this rhnlib >= for centos 5.4 or el5.4 
rpm!

any advice here would be nice
