new redhat/fedora user

[Aaron Stromas <passogiau gmail com>]

Hi, 

I am a longtime Debian user that need to set up mail services on this
x86_64 preloaded with Red Hat Fedora 3. I'm trying to install the Clam
antivirus RPM clamav-data-0.87.1-1.fc3.
It depends on fedora-usermgmt but when I triy to install fedora-usermgmt-0.8-1  it fails complaining that the dependency fedora-usermgmt isn't available - a circular dependency?
I'm installing from http://fedoraproject.org/extras/4/x86_64/repodata/index.html.
Any idea how to resolve thei catch-22? Isn't there a tool on RH that
downloads/installs dependent packages, like apt-get/aptitude on RH?

Regards,
