Kate, I tried to install the Mandriva rpm of the baghira theme on my the computer. Then, I moved all of the files where they should be. (In KPackage, I was able to see the list of the files and where they were uncompressed)
It doesn't work. Trinity is probably not binary compatible with KDE3 anymore, so the theme would have to be re-compiled from the source, something that I don't know how to do... Probably some persons here know ho to do it?
One thing, Francois Andriot did not specified the right text file for the repos lists. The repos lists in PCLOS is in:
/etc/apt/sources.list
This is the file where the url of his repos should go.
