If you're like me, then you have got most of the FOSS packages built and installed already, and are mostly fiddling around with KDE4 sources themselves, or with new packages.
There have been some changes in the way CLucene is compiled, in order to force the definition of float_t to something sensible. This means that if you try to compile kdesupport now against an older (like 2 weeks or more) clucene 0.9.19 then the float_t's are mismatched: rebuild CLucene to update to 0.9.20. Of course, when you do *that*, you end up with the weird CMake error reported earlier on this list, regarding CLUCENE_LIBRARY_DIR. I'm looking into that.
