TDE on SID

Hello all, This is NOT a complain, just a question. While I'm working with a perfectly working Wheezy + TDE, I've had the curiosity to install "Siduction", a rolling distribution based on SID. I've tried to install Trinity Desktop from the nightly builds (using jessie as target distribution). desktop-base-trinity installed correctly, but kde-trinity depends tde-trinity taht won't be installed. My question: does this mean that Trinity and SID are incompatible (which I would understand, given that it's impossible - and makes little sense -to provide compatible packages) or is it one of these situations where packages are just being (re)created for Jessie and I should try it later. ANd if so how can I know when such a situation occurs? Siduction is not interesting if I can't get a sensible desktop... Regards, Thierry
