This is the answer from our lawyer, Devin Smith. Sorry it took so
A programmer who -- with the permission of the copyright holder --
creates a derivative work based on another work actually owns the
derivative work. So, since the programmer of the derivative work owns
it, there's no need for the owner of the original work to grant that
programmer a license to distribute the derivative work.
Now, that doesn't mean that the owner of the original work can't put
contractual restrictions on what the programmer of the derivative work
can do with the derivative work. The Boost license, for instance,
requires programmers who develop derivative works to include the Boost
license with non-object code distributions of the derivative work.
