I'm trying to learn Roassal, but I can't seem to get the first visualization from
https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/QuickStart/0101-QuickStart.html
working on any combination of image and vm. I've tried the vm+40 and vm+50 from get.pharo and the moose 6.0 image from the moose site.

The issue seems to be that CairoLibrary>>unixModuleName does not contain the /usr/lib/x86_64-linux-gnu/libcairo.so.2 path where 64-bit Ubuntu installs cairo. If I symlink that library, I get an Error: External module not found from AthensCairoSurface. I don't really know enough about the external module system to know what this is telling me. Any ideas would be much appreciated.
