Its easer than other linux distribution that there is a Redhat install package available at http://www.real.com/linux/
unfortunately the click able link to download the rpm package doesn't work on my Firefox browser that built in by fedora 8. it display a blank page only. neither the clickable download realplayer link works.

well, why i trying to download a opera browser for linux, i found there is a project called helixplayer.
all realplayer that build for linux/unix/symbian can be downloaded from https://player.helixcommunity.org/

where i found the most updated package that released 2 months ago.

RealPlayer 10.0.9 Gold (6.3M) https://helixcommunity.org/projects/player/files/download/2479
and
Helix Player 1.0.9 Gold (4.0M) https://helixcommunity.org/projects/player/files/download/2488
