ppc, I had to drop the ~ppc keyword from dev-ruby/heckle-1.4.1 because this version now depends on dev-ruby/zentest, and zentest is not keyworded for ~ppc. Could you have a look and add the ~ppc keyword back to dev-ruby/heckle and to dev-ruby/zentest? Given that this is all pure ruby code I think it should work fine on ppc, but better to actually test it. :-) CCing robbat2 as well, as I believe he uses this stuff for work on ppc, so he may be able to do the keywording.
my ppc box is down for at least the next week, but i'd wager that zentest probably works.
