If you mean that the RPM won't install, I have no idea.
But to run it, I needed a script like:
#!/bin/sh export LD_ASSUME_KERNEL=2.4.1 exec /usr/lib/RealPlayer8/realplay $*
I put in /usr/X11R6/bin in place of the realplay sym-link.
Also, since I'm not using the bigmem kernel, this may be a waist of bandwidth.<g>
