Just to avoid going in the tool issue again. Could you reproduce this problem on a plain Pharo3 + Roassal image? Then we can announce the image on the Pharo mailing list and see if we can get help.
In a 30851, with the 355 vm (Mavericks), opened a workspace,
Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load
loaded an old version of Roassal2
If I open RoassalExamples in the world menu, I get a red window.
Opening the settings, unselecting and reselecting FreeType doesn't help. Setting the standard font to Helvetica Neue and using that as default font for everything makes Roassal2 work.
