rpm install issues - RHE3

i need to install PostGreSQL 8.0.1 on my RedHat Enterprise 3 server.
i'm using the postgresql-8.01-2PGDG.x86_64.rpm package, and it's
paired server package. i get a lot of dependency failures on an rpm
-ivh command, but when i check to see if i have the required
dependencies everything seems to be there. can someone tell me if
there's a better way i can do this? i am hesitant to compile from
source because of all of the rpm problems. i'm still relatively new
to Linux and very new to PostGreSQL

thanks in advance!
