I've started looking into that. However, my strong suspicion is that the way to build a MacPython installer that can use a user-installed Tcl/Tk is to *have* a user-installed Tcl/Tk installed before building python

That's one way, another is to use install_name_tool as part of the
build procedure to change what _tkinter.so looks for, and a third is
to include a subset of a recent Tcl/Tk in the build like the Win32
installer does. The third option is ideal as far as how we do
everything else goes.

I confess I've not figured out how this would work. Where would the
installed Tcl/Tk go, to avoid colliding with a user-installed Tcl/Tk.


still not completely stable and the user should easily be able to
upgrade to a newer (less buggy) version if one comes along.

I'm a bit happier using a user-installed Tcl/Tk (if found) because it's

Personally, I don't care much about this issue. I don't use Tcl/Tk
Aqua, and it seems the only third party builds readily and obviously

patch makes it a lot more likely that something will happen

I wasn't sure what to patch, so I submitted bug report #1563046.

The bug report includes a python script that (based on your recipe)
modifies _tkinter.so to use a user-installed framework Tcl/Tk if it
finds one.

I'm hoping the script will run as part of the installation of MacPython.

As I noted in a comment in that bugreport I'm not to keen on that. I don't mind shipping the script ( or a GUI version of it) in the application folder for users that want to switch to a newer Tk, or even ship a minimal version of Tcl/Tk inside the Python.framework, but running this script during installation means that (a) the script must be 100% correct in all situations and (b) we'll end up with Python installations that are slightly different which won't be fun to investigate when someone reports a problem with tkinter. Especially because users might not even realize they have a copy of Tk in /Library/Frameworks.
