Here&#39;s what I did to get it partially working on my AVLinux2rc2 (debian) installation:<br><br>export QT_DIR=/usr/lib/qt4 (not sure if this is needed)<br><br>then <br><br>QTDIR=/opt/lib/qt4 scons (not sure if this is needed)<br>

<br>it returned these errors: <br>[...]<br>ary/moc_SoundLibraryTree.o gui/src/PlaylistEditor/moc_PlaylistDialog.o -L/opt/lib/qt4/lib -lQtGui -lQtNetwork -lQtXml -lQtCore libhydrogen.a -lsndfile -llrdf -lFLAC -lFLAC++ -ljack -lasound -ltar<br>

<br><br><br>Then I upgraded the following packages:<br>libxslt1-dev (1.1.24-2) to 1.1.26-1<br>libxslt1.1 (1.1.24-2) to 1.1.26-1<br><br>and now it installed fine, only problem is no drumkits are installed by default.<br><br>
