PhantomJS: error while loading shared libraries

I’m getting the following error when with phantomjs. I’m hosted in Modulus and am not sure if this is a Modulus problem or a Meteor problem. It works fine on my local box. Does anyone know if there’s a way to install libfreetype through Meteor/npm to resolve this or is this a Modulus issue?

phantom stderr: /mnt/app/node_modules/phantomjs/lib/phantom/bin/phantomjs: error while loading shared libraries: libfreetype.so.6: cannot open shared object file: No such file or directory
