Er.. the GPL doesn't require that the IBM source be distributed under
any terms other than the IBM license -- it merely requires that the IBM
license allow the same permissions as the GPL.

Currently the IBM license explicitly states that the GPL's transitive
property isn't allowed, so that's enough to prevent satisfying the GPL.
But I was looking for some other specific conflict.

[If this is the only conflict, that's fine, I just want to make sure
I understand the issues.]
