Since Eric has posted his work related to KDE 4.5 Beta 2 on his blog, i took a chance to pull his work into our local repo server using rsync to his alien-kde repositories and soon, it will be accessible by going through: http://repo.ukdw.ac.id/alien-kde/4.4.85.
There will be new dependencies as well, so make sure you have installed all the dependencies before upgrading and testing KDE SC 4.5 Beta 2 on your system.
WARNING: KDE SC 4.5 is still in Beta and NOT RECOMMENDED for daily usage system, unless you are a tester or developer who need to try latest KDE version or you are willing to take the risk of having an unstable desktop.
Update (12:36 PM): The repository has been fully synced with Eric's KDE repository now. Everything is mirrored on the repo and it has all the READMEs included in each directory. Enjoy the repositroy
