I don't know about the toolkit, but I just finished compiling vic and
rat for Gentoo PPC from the CVS ag-media tree. I had issues in the
past with rat not working, but it seems the CVS tree has this fixed.
I had previously released AGTk 2.3 for Fedora 4 PPC, at the time I wasn't
using ag-media from CVS, but Steve Smiths darcs repository.
I've just CVS checked-in a fix to AccessGrid/Platform/unix/Config.py to
support the PPC endianess with Video4Linux
