Centos: dependency-problems, how to solve?

Hy!

On my Centos5-client I have manually installed some perl packages some time ago, unfortunately I dont remember what my repository settings have been before. I know I have excluded clamav and spamassin from Centos-repositories, so I assume I need rpmforge too, but i am not sure any more. Yum-update gives me these results - please help me to make yum update the other packages again. Thanks!

 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

rmp -e perl gives me a huge list including spamassain, mysqlserver etc, so just removing perl completely wouldnt be an option, I think I now remember that what I tried was to install a perl version that was not yet included in centos..`[/code]
