but there are no build problems with the same source package in Quantal, see


I don't understand why build from the same source fails when building for Ubuntu 12.04 (precise), maybe I should use newer version of dpkg-dev or debhelper?

It seems problem was in older dpkg (or dpkg-dev) version, which is in Ubuntu 12.04 (Precise) - I've copied backported dpkg 1.16.7ubuntu3 into Baltix-Members PPA and now embryo 1.2.0 builds fine for Ubuntu 12.04 :)
Btw, I've found simmilar problem described in bug #935394

Thanks for tip, it seems these packages are backported for smart phones (SHR-Project), but should work fine on desktop too ;)
