We have repackaged qt-3.3.8 and included Daisuke's immodule-qt patch in this build. The immodule-qt patch will allow for multiple input methods to be used with qt-based and KDE-based applications. Any applications built against unpatched qt-3.3.8 are binary compatible with this patched qt.
This package is in the VL 5.9 testing repository here: http://vectorlinux.osuosl.org/veclinux-5.9/testing/libs/qt-3.3.8-i586-5vl59.tlz
The build scripts and patch files will be uploaded later.
