Unless I'm wrong, the source used by Debian packagers (which is our reference version, as always) is the code provided on pypi 


which looks like up to date with the code on github.

So pip *should* work fine with yapps2 now, and unless I'm wrong, the only place we need to do something 
is in rql so it does not rely on the (now useless and deprecated) dependency_links processing.
