[Pharo-users] Can't find Cairo

Heya, I need some help telling Pharo where to find things. I've installed Bloc into my image, and it can't find cairo. Cairo is installed, but as far as I can tell Bloc is not looking for it in /usr/lib/x86_64-linux-gnu/ which is where it can be found. I don't care to go making symlinks around my system: is there a sensible way to tell Pharo where to find libcairo? Thanks! -Steven
