building qtractor and other QT-apps

As I try to build apps based on QT3/KDE/QT4 I run into several problems.

Qtractor and Traverso need qt4 devel packages to build libqt4-dev is not installable due to trivial dependency-conflicts

Rosegarden needs KDE-dev but if I install this I need to de-install XFCE first So I switched to KDE and will try to build XFCE from scratch to get back my standard-desktop.

Is there anybody aware of this problems?

I tried to hack the

I tried to hack the situation by simply forcing the install of qt4devel and coying its files so apt cannot erase them, if I later allow it to repair its database.

Yet to no avail:

/usr/bin/ld: cannot find -lQtXml

qtractors configure script does not complain anymore but make fails to find a component in QT4-devel it needs.
The stupid hack I performed does not help anyway:

-- Traverso 0.42.0 will be built to install into /usr/local
-- Program pkg-config found (/usr/bin/pkg-config)
CMake Error: Could NOT find QtCore.

copying some files into /usr/include is one thing hacking pkgconfig is most different so I give in here and hope, these dependency-issues will be fixed so I dont need to switch to Ubuntustudio to have these apps running. I´d really would prefer to stay with 64Studio for its superior performance though...

Repositories

Try activating the testing and backports repositories -

# Bleeding edge 64 Studio repository, only for testers!
deb http://apt.64studio.com/64studio/testing/ 64studio main

# Backports repository, needed to get -dev packages
deb http://apt.64studio.com/backports/ etch-backports main

These should be available in your synaptic repository selector. If not, add them...
