Title:
  Please update gtkmm to 2.22

Status in “gtkmm2.4” package in Ubuntu:
  In Progress

Bug description:
  Binary package hint: libgtkmm-2.4-dev

Ubuntu 10.10 (Meerkat) has GTK+ 2.22 but it only has gtkmm 2.20. This is the first time in a long time that it's got out of sync so I guess something is wrong.

It's annoying not to have the new API but it's particularly awkward because it is then impossible to build some software while disabling all deprecated API, due to the way the versions of the headers depend on each other. Disabling deprecated API is a very useful and common practice for developers, but you are likely to see errors such as this, which I will paste for the sake of people using Google in desparation:
