The slrn package seems to be missing.
I could not see any mentioning of it being removed from the distro in the
releasenotes and the fact that bugzilla knows about the slrn package seems to
support the idea that it is just an accidential omission.
Please do include the slrn package again as an update to the current rhel4 distro.
