Well my problems are practically solved, except for one (blackdown-jdk).
The 2 broken dependencies of the kded_mediamanager.so where solve
removing one of the two / as you mentioned.
The broken dependency of xterm was solved by manually re-emerging xterm
(no revdep-rebuild did not do it automatically, maybe some little bug?)

But for blackdown-jdk, I just don't know how to tell revdep-rebuild not
to re-emerge the package.
My gentoolkit version is 0.2.1, I am running stable arch and I do not
need sound (it is a server, no sound needed).
