Hi there, Im trying to compile garnome 2.10 on debian testing. Everything is going swimingly, solving dependencies as i go.. but here is one i cant find a package to solve:

make[4]: Leaving directory `/root/garnome-2.10.0.1/desktop/gnome-utils/work/main.d/gnome-utils-2.10.0/gdictsrc'
Making all in gnome-screenshot

Can someone suggest a debian package i need to install here to solve this?

Thanks plenty
