Fwd: Qt on PowerPC

Hello Kubuntu Developers and Jackson,

I'm skeptical as to using an unofficial port of the V8 engine for just one
architecture. After all, unofficial items should NOT be accepted into the
Ubuntu archive at all.

Jackson, do you think you can communicate with the person who ported the V8
engine to PowerPC to try and make it official?

Personally I would want the entire PowerPC architecture port in Ubuntu
killed, but my opinions about PowerPC do not comply  with the general
opinions of Ubuntu, Lubuntu and Kubuntu communities on the same matter.

Nevertheless, I am not willing to see a V8 engine in our archive that is
unofficial. But, we can wait probably until the official release of KDE
Frameworks 5 and Plasma Workspaces 2. Then we will have to see if we can
make the V8 engine official, or we just can't support Qt 5 on PowerPC. We
can still support KDE Software Collection 4 for PowerPC users if the latter
has to happen.
