I was kinda disappointed i can't properly install xfce 4.6 on debian lenny with aptitude. Also tried backports with issues like here: http://www.linuxquestions.org/questi...ys-4.4-775588/
I decided to go the proven (cloacms
++) way of building from sources.
So, i fetched all(almost) files from http://mocha.xfce.org/archive/xfce-4.6.1/src/
and started building. I removed my xfce 4.4 installation and built libraries...
