OSSAL/CC license of xMule parts
I'm currently preparing an updated xMule package and found a statement,
which sounds a bit problematic. But I'm not a lawyer, so I ask you. E.g.
// This file is dually licensed under the terms of the following licenses:
// * Primary License: OSSAL - Open Source Software Alliance License
// * See the included License.OSSAL for complete details.
// * Key points:
// 5.Redistributions of source code in any non-textual form (i.e.
// binary or object form, etc.) must not be linked to software that is

I'm not sure of any of these licenses is DFSG-free. AFAIK the CC
licenses are considered non-free and I'm concerned about the OSSAL too
(that forbids linking against GPLed libraries). And the exceptions don't
seem to allow Debian to link against GPLed libraries.
Can you clarify the situation?
