Matplotlib maybe? Federico?
Yes, given that the back-end currently used by matploblib doesn't work, I would change that by using 'Tkinter'. Since you are at it, I would also change the default back-end by changing 'GTK3Agg' to 'TkAgg' in the following snippet: (lambda (port) (format port "[rc_options]~% backend = GTK3Agg~%"))))) I'm not convinced that having 2 versions of packages (a "normal" and a "minimal" one) is a good idea. The reason is that you often end up downloading both instead of just one. As one example, I just downloaded 'vlc' and I noticed that it downloaded both 'cups' and 'cups-minimal'. Similarly, for python, anyone needing 'Tkinter' will end up with 2 versions in the store. Regards, Fede
