Zombie flesh is now canned as a poisionous can, or 'looks bad'. You are supposed to be able to re-can bad cans into good cans as the wiki describes, but the is apparently a bug that prevents that. IC2 has been updated, but I think the #232 update just after the version that Tekkit Lite uses changed over to MC 1.5, thus making future versions incompatable with Tekkit Lite.

If there is a dev out there that can stub out a version that has this canning issue fixed, perhaps call it 'industrialcraft-2_1.115.231.1-lf.jar' and slip it into the next Tekkit Lite, that would be nice. Unles the next version is moving to 1.5... =]
