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:
