It is allowed to copy and redistribute code under the terms of the APSL.
http://www.opensource.apple.com/apsl/

It is not allowed to put derivatives or portions of APSL-licensed code
under the terms of GPL.

Well, does looking at the code + thereby learning about the implemented
ideas/algorithms + re-implementing the ideas/algorithms + licensing the
result under own terms qualify as legal? This is a somewhat rhetoric
question since it is hard to tell how independent a re-implementation is
once the re-implementor read the source of the original implementation.
