Citation for 'Apacher v2 is not compatible with GPL2?' I thought it was a permissive, essentially BSD-style licence with an additional grant of patent use, so it would be compatible with GPL in the same way the BSD licence is compatible.

It doesn't matter, because libdispatch accounts as 'system library' - see GPL FAQ for explanation what system libraries are and why GPL applications can link against them, regardless of their license. (For example, GPL-ed applications under Windows can link against Microsoft-provided DLLs.)

The system library exemption only covers the case where you're distributing the code that uses the library separately. Traditional interpretation in the Linux world has been that this prevents you using this for a non-GPL compatible library if other libraries or applications in the standard install make use of it.
