Due to the experimental nature of this release, binary packages are not being made available via the KDE mirrors. Some distributions may provide binary packages on their website, however, so please check there if you are looking for binary packages.
That pretty well covers it, I wouldn't count on too many standard distro makers spending a whole lot of time making rpms out of an alpha release knowing that it will likely change very quickly. I could be wrong
, but I don't think so!!
