When I unzip or untar or whatever the proper term is pjproject-2.3.tar.bz2 it creates files and folders with non-standard users. There is no switch in tar that lets me ignore these. The group user ownership it unzips as is "games". The user ownership is "501" meaning non-existent on my system. Must have been a custom user on the creators system. Yes it's easy enough to just chown -R and this does not seem to have any effect on compling as root user. However, as far as I know it is standard practice to create these with default root ownership.
