Purr Data trying to load externals with tcl gui objects
I've only tested this in OSX, but purr tries to load libraries in the default externals path at ~/Library/Pd. Some of these (e.g. moonlib, cyclone) have tcl gui objects, and of course won't draw. Not sure what to do about this one because we do want to to be able to load externals not packaged with purr data. Maybe not have them load automatically?
