I did the same procedure as for Pup525 and of course Python was first installed.live, I just installed Python 2.6 and Openshot 1.3.1 from the Puppy Package Manger and it seemed to work. It started and loaded and played an mp4 video anyway. (I am using the pre-266 luci though.)
You must install python first, and you must ignore the errors. I am irritated with PPM because those are not real errors--the libraries are just not where PPM expects them to be. Sometimes I can do some slight of hand to conceal the "errors" but not in the case of Openshot. I have requested the ability to turn the error checking off because all of the packages in the puppy-lucid repo are checked already, but that hasn't happened. Any hackers???
Python & Openshot 1.3.1 from PPMThe errors you show are missing Qt files--perhaps you had a different Openshot?
