libgtk-3-dev - unmet dependencies on install

Hi,

Trying to install GTK+ v3 on my Trisquel installation, however the install result in a "unmet dependencies" for libpango1.0-dev and libcairo2-dev.

Anybody with a clue?

//Install
sudo apt-get install libgtk-3-dev (Which should be suffient)

//Result
The following packages have unmet dependencies:
libgtk-3-dev : Depends: libpango1.0-dev (>= 1.30.0) but it is not going to be installed
Depends: libcairo2-dev (>= 1.10.0) but it is not going to be installed
