hi, here's how i built (seemingly mostly working) kdenlive on a minimal mixed intrepid/jaunty (upgraded from hardy via apt) ubuntu system. i come from debian, so i don't use many of the gui tools provided for package management in ubuntu. console freak. so, :
my /etc/apt/sources.list:
deb http://packages.medibuntu.org/ jaunty free non-free
deb-src http://packages.medibuntu.org/ jaunty free non-free
deb http://us.archive.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
# kdenlive
deb http://ppa.launchpad.net/baudm/ubuntu intrepid main
deb-src http://ppa.launchpad.net/baudm/ubuntu intrepid main
deb http://packages.medibuntu.org/ intrepid free non-free
deb-src http://packages.medibuntu.org/ intrepid free non-free
deb http://us.archive.ubuntu.com/ubuntu/ intrepid main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ intrepid main restricted universe multiverse
i removed kdenlive ffmpeg amd mlt
sudo apt-get remove kdenlive ffmpeg libmlt*
installed basic libraries for kdenlive
sudo apt-get install libqt4-dev kdelibs5-dev libsdl1.2-dev libsdl-image1.2-dev libxml2 libxml2-dev recordmydesktop dvgrab libdv4 libdv-dev x264 libx264-65 libx264-dev libtheora0 libtheora-dev libxvidcore4 libxvidcore4-dev libogg0 libogg-dev libvorbis0a libvorbis-dev libschroedinger-1.0-0 libschroedinger-dev libmp3lame0 libmp3lame-dev libquicktime1 libquicktime-dev libfaac0 libfaac-dev libfaad0 libfaad-dev libgsm1 libgsm1-dev libamrnb3 libamrnb-dev libsamplerate0 libsamplerate0-dev libjack-dev sox libsox1 libsox-dev ladspa-sdk swh-plugins libmad0-dev frei0r libgdk-pixbuf2 libgdk-pixbuf-dev libpango1.0-dev yasm automake git-core libfrei0r-dev libgtk2.0-dev kdesudo subversion kommander
download builder wizard at http://kde-apps.org/content/show.php?content=85826 and unbzip-it:
bzip2 -d 85826-kdenlive_builder_wizard.kmdr.bz2
make a src directory somewhere (mine was /root/src/)
run it with kommander:
kmdr-executor 85826-kdenlive_builder_wizard.kmdr
hope it comes handy to someone.

yes, this is 32bits, kernel is i686, the machine is intel quad core2 with 64bit support, but i'm not using it.
