ubuntu too?

A user asked if the p.d.o repository would work with ubuntu. A quick check showed that it would not work (libc version conflict), but I guess this is just a false dependency and a quick rebuild should solve it. But I would rather not keep up with 2 build systems and 2 bts. So googling for 'debian developers faq to ubuntu' got me nothing.
I fear I will have to start listening to Queen and talk to the MOTU :-).
