Hi everyone,
Thanks to the help of several people, there are now recent development builds of Inkscape for PowerPC (G4-G5), as well as prebuilt python modules for all machines (ppc and intel) and all python versions currently available on OS X (2.3 - 2.5). These new builds are available on modevia as usual: http://inkscape.modevia.com/macosx-snap/?C=M;O=D
Python packages are integrated into the application so drag Inkscape and drop it somewhere on your machine (e.g. in Applications) and everything should "just work". There are two PPC packages (dec24 and 16774) which should work on Tiger and Leopard and one i386 (Intel) package (16834) which, unfortunately, is Leopard-only.
These should be still in time for the about screen contest and will provide good testing for the release.
Cheers to all those involved in PPC compiling.
