apt-get install libsdl-ttf2.0-dev

The following packages have unmet dependencies:
libsdl-ttf2.0-dev: Depends: libsdl-ttf2.0-0 (= 2.0.9-1maemo2)
Depends: libc6-dev but it is not installable or
libc-dev but it is not installable
Depends: libsdl1.2-dev (>= 1.2.4) but it is not installable
Depends: libfreetype6-dev but it is not installable

Any ideas?
