Help installing Nmap

[El C0chin0 <mr.nasty () ix netcom com>]

I'm trying to install nmap-3.50xxx.rpm on a redhat linux 9 box.  When I run the rpm command with the -U switch I get:

  error: failed dependenices:
       nmap = 3.00 is needed by (installed) nmap-frontend-3.00-4.

I've looked all over the place and don't have time to read the history of nmap and the internet to figure out how to 
install the frickin package.  Does anyone have a quicky fix for this problem?

Thanks in advance.
