We have some Jenkins jobs building libanon, libdclass and libcdr whenever a patch is proposed in Gerrit. Hence the -dev packages are installed from apt.wikimedia.org on the instances running the compilation.
This week I have pooled an Ubuntu Trusty instance, and puppet complains because it can not find them for Trusty.
From a quick discussion with Christian, libdclass is probably no more used. But libanon and libcdr could use a Trusty version.
Marking as blocking bug 68256 which is about finishing up the setup of Jenkins slaves with Trusty.
