I'm afraid you are. Although I'm not 100% sure -- I don't remember
exactly how GPL is applied to source-only distribution and I don't know
well enough which parts of john are under GPL, who their authors are and
how they interact. Maybe license exception from Solar is enough but
maybe not.

I think it's possible to distribute rar support as a standalone patch.
If you can separate rar support from the rest of john and make a patch
which doesn't include anything GPL'd then it should be distributable on
its own.
