libggi uncorrectly assumes that all ppc boxen are embedded motorolla products in their configure script and set to build a non working lcd823 (embedded lcd controller) for anything ppc.(vendor code problem). Workaround, patch for their default configure to remove this problem. Vendor should be contacted (this has been in there code since 2000-05-11).
ebuild and patch tested on ppc and x86 and committed.
