A Fink package of Pd-extended would be quite nice. Tigital has been talking about it because it would be faster and the GUI will use less CPU.
I will take a look at it. I don't have a whole lot of time at the moment so don't expect any results within the next few weeks. Although I have a feeling that most people using Macs prefer the look of the Aqua interface I think it would be nice with the choice of being able to easily install and run pd under non-aqua X11.
The C code will probably be easy to get going, but there is going to be some added checks on the Tcl/Tk side of things (pd/src/u_main.tk aka pd.tk). Basically, the GUI only checks the OS not the Windowing engine. So you'll have to add checks to pd/src/u_main.tk. In an installed app its known as bin/pd.tk, but its the exact same file.
This is the command you'll need: tk windowingsystem
which returns one of
aqua win32 x11
tk::mac::useCGDrawing is a Tk/Aqua-only command, so that might be the only change needed.
Thanks for these tips.
