I can't guess at if or when there will be a clucene release. However the released version is 
ancient, and the developers themselves say the git version is stable and should be used. On the 
other hand, I don't think distributions carry it. I could look into using the released 
1.9.x-compatible version instead, but I expect there was a reason for using Lucene 2.3.x. There is 
a tag for clucene-src-2.3.3.4 for which there are also tarballs on the sourceforge page. We could 
depend on that version -- it is a small dependency and takes under a minute to build.

Regarding the contribs: it is part of their git repository, and can be enabled as part of the 
standard build.

I'm planning to work on that later today. (But also see the post by Caolan, which you may have 
missed.)
