Hi,
I am the maintainer of AV Linux a small independent multimedia ISO based on 32bit Debian Squeeze. Over the last few years AV Linux has grown and built a reputation for providing a stable platform for both audio and video applications and is the official LiveDVD for Openshot and LiVES, it has been my pleasure to also provide Kdenlive although you guys don't make it easy! I am writing this in addition to this post on my forum: http://www.remastersys.com/forums/index.php?topic=2451.0
As the post above indicates Kdenlive currently is at a place currently where it will be no longer distributable for the soon to be released AV Linux 6.0, as I was careful to indicate this is due to a variety of factors and I'm not questioning the development decisions made by the developers of Kdenlive or MLT because they are none of my business. I will let you know for you own consideration that AV Linux sees about 10000 FTP downloads in an average month and probably an additional 1000 torrent downloads, these are small numbers compared to giant distros like Ubuntu but I can honestly say other than users of your kdenlive-svn PPA that AV Linux gives one of the best OOTB user experiences out there with Kdenlive and it's NLE contemporaries. It is unthinkable both to myself and many other users that Kdenlive will not be available on the next AV Linux release (without using the build scripts). At this point I will switch from 'note' to 'plea' and ask if any of the following options would be possible:
1. Make MLT fully compatible with both ffmpeg 0.7.X and 0.8.X...yes I'm dreaming big!
2. Make Kdenlive 0.9.2 compatible with MLT 0.7.6 which was the last fully functional version compatible with ffmpeg 0.7.X and is also the best performing version with Openshot 1.4.2+
3. Provide a GIT checkout URL for a snapshot between 0.9.0 and 0.9.2 where MLT 0.7.6 was still valid.
Let me be clear that although this is a frustrating issue it is my intention to be constructive and not critical, I hold Kdenlive in very high regard and it has earned it's place as the most fully featured Linux NLE through countless hours of your hard work, I simply want to continue to provide a good working example of your combined efforts to the growing number of AV Linux users.
Please consider my request and in any case thanks for taking the time to read it.
Sincere regards, Glen MacArthur - AV Linux Maintainer.

OK,
Well since no reply has been forthcoming after several days I have ended up building Kdenlive 0.9.3 (GIT) from the build script and creating a Deb package that installs to /opt. This is a disappointing workaround however not quite as disappointing as the complete lack of acknowledgement by the Kdenlive developers.
In any case sincere thanks for the build scripts since without them Debian Squeeze users would be out of luck.
