Or even better: how can I update Inkscape 0.91 + XQuartz on Mac to 0.92?
I followed the instructions in the download page to install 0.91 few months ago and it went fine!
But I have no idea on how to uninstall 0.91 to install 0.92.. but I'm very happy we have it available in the MacPorts... seems like an elegant, and yet simple, solution.
Sorry for the silly question.
