Comment 1 for bug 701833

I attempted to perform a backport of vlc 1.1.5 on my Karmic machine using pbuilder but the build failed due to unmet dependencies. How can I configure pbuilder to use older dependencies or use the dependencies already installed on my machine. What method would backporters use to backport packages, i.e. do they use their own machines to backport or is the building done via Launchpad servers. How can I debianize the source code and then use pbuilder to build the package?
