Reusing APSL-/GPL-licensed code

[Clemens Lang]

Hi,

for my GSoC project, I would like to reuse code from Apple's cctools
package, in specific code from within otool[1].
The package is dual-licensed[2] under APSL 2.0[3] and GPL 2[4]. Since
MacPorts is BSD-licensed and APSL 2.0 and BSD don't seem compatible (I'm
not an expert on licenses, correct me if I'm mistaken here) and GPL 2 is
definitely not BSD-compatible, is there a way I can reuse that code?

I'm thinking of paragraph 4 in the APSL:

> 4.	Larger Works. You may create a Larger Work by combining Covered
> Code with other code not governed by the terms of this License and
> distribute the Larger Work as a single product. In each such instance,
> You must make sure the requirements of this License are fulfilled for
> the Covered Code or any portion thereof. 

Is it possible to use this code within MacPorts? Are there any
precedents for this case?

Regards, Clemens
