Assuming you mean GPLv2 only, the answer is that both situations have
compatibility problems. You should ask upstream to try to resolve the
incompatibilities. The simplest way to do so would be to relicense the
GPLv2 only files to GPLv2 or later (Note: You'll probably end up talking
to both the OpenERP upstream and the 3rd party upstream).
