There is a problem with cmake-2.4.7 and the CMakeLists.txt qt4-qtruby-1.4.9 uses. So only the symlink to qtruby4.so gets installed, not the lib itself. This leads to loaderrors. Reproducible: Always
Created attachment 127414 [details] qtruby4-cmake-2.4.7.diff I found this patch here: http://rubyforge.org/tracker/index.php?func=detail&aid=12566&group_id=181&atid=761
should be fixed now in portage thanks for the note.
