[1.33][SMP/SSP]Turtles cannot place BuildCraft pipes

Turtles cannot place BuildCraft pipes.Turtle.place() will always return false and nothing will happen when pipe is selected.

RedPower2 pipes are also unplaceable, but with those it appears like placing was successful (turtle.place() returns true, item count decreases etc.), however no block is actually placed.

That is a known bug, but I think dan is working on it. So let's hope for the nexxt release. until than, you can only place things whose itemid is smaller than 256 and whose metadata is smaller than 16. Use NEI or TMI to check if unshure.
