As I tested on amd64 and i386 should be sufficient to rebuild libr. Is already uploaded into my deps-r14 ppa, ready for the amd64 and i386, for armel and armhf build wait in queue:
Slavek, Tim, I did a full rebuild (amd64) yesterday and everything looks good again with tdelibs and libr. I have a new FTBFS for tdenetwork (missing libgadu) but haven't got the time to look into it yet.
Cheers Michele
