Is the license:

enforceable? Of course not. It contains an illegal condition.
I am not a lawyer but I'm sure a license cannot require you to
murder your mother. But one could interpret the above
hypothetical license as simply saying that you may not, under any
(legal) circumstances, copy, make derivative works, or
distribute the specified works.
Consider a license that says:
You may copy, make derivative works, and distribute those works
that are based on the covered source code provided that you first
compute to the last decimal place the value of pi.
The condition is not illegal, merely impossible. I'd say that
the above is equivalent to:
You may not copy, make derivative works, or distribute those
works that are based on the covered source code.
