Current weka should be renamed to something like weka-devel. Although a

development upstream is pointless, there is no reason not to be using
this branch." , there still exist users who want to use a stable
package. So a rename is necessary to clarify.
And if possible, orphan it as well, several packages of the maintainer
are out of date.
