Hi Ken,
Please don't install any version-specific RPMs, you would
be begging for trouble in doing so.
The yum installer should be good enough for you, just
specify the package name. Note that I am not 100% sure
that Xp is a Core6 package, though it is in Fedora (no
longer Core) 7. If not (which is unlikely), the command
below will just tell you the package is not found.
I don't know if you plan to compile yourself, or just to
run the AFNI applications, but maybe it's best to install
the developer headers, too, just in case.
So install these packages (as root):
yum install libXp libXp-devel
