It's out now.
just committed the ebuild, please test and report success/failure.
I just emerged it (and xft 2) and after a restart of X everything seems to work just fine.. (I had some programs crashing due to some font stuff earlier, but they work fine now).
marking as fixed cause qt-3.1.1 is in portage. it is currently package.masked cause bug #12538 is not resolved. it is also missing /usr/qt/3/include/qtmultilineedit.h which is needed by /usr/qt/3/include/qmlined.h, so it will probably ever stay masked. thanks.
