This worries me just a bit. We do not want to duplicate libraries and other dependencies that are already present in Lucid Puppy. Probably you have already accounted for that.You can use Pdebthing to download DEB packages with all, but ALL their dependencies.
Very often in my experience, Ubuntu will report dependencies that are extreme. For instance, it reports Midori as needing 74MB of dependencies. However, someone built (maybe me I can't remember) a Midori with Ubuntu binaries that "only" needs 39MB. Then the shared Midori that technosaurus built in Puppy only needs 17MB--and that is the same version of midori and close to the same webkit.
Most of the time in building packages from Ubuntu they need some manual tweaking and adjustment. I don't want to sound discouraging though--the more good packages for Lucid puppy the better! So, make them and post them for testing and let's go forward. Thanks.
