MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Puh, apparently 2015.03 can't handle this syntax style either. I knew 2014.03 couldn't (since it's my debian standard package), I don't have the 2015.03 available for testing.
Honestly even if you are new to OpenSCAD, give the Nightly versions (Development Snapshots) a try. The 2016.XX versions also offer a bunch of new features, faster rendering etc...
