I don't know, but this is probably old news for most RH users, but I've only been using RH 8 for about a week now. I was very frustrated trying to find RPMs over the internet and it seems to me that the package manager that comes with Redhat is a POS. After experiancing the pleasently wonderful apt-get system in Debian, Gentoo's amazing portage system, and OpenBSD's ports I found RedHat's solution seriously lacking.
But I found a port of debian's apt-get that has been modified to grab rpms instead of of dpkgs. It was originally created by Conectiva but it works well with Redhat... This combined with a graphical interface called synaptic, (sort of graphical equivilent of dselect) it is realy nice to use.
You just goto Freshmeat and get the apt-get package...
install that then run
apt-get install synaptic
(note you must be root or it will complain about not getting a lock on a file...)
then synaptic should be in the system settings folder....
hope someone finds this usefull
