Currently blocked on ABI compatibility issues between XQuartz (X server) and the Tcl/Tk shipped by Apple:

Tcl_Interp *tcl = /* ... */;
// Segfaults...
DefaultColormapOfScreen(
    XDefaultScreenOfDisplay(
        Tk_Display(Tk_MainWindow(tcl))));

Can possibly be overcome by using a third-party Tcl distro like ActiveTcl.

So I don't forget.

I've made some progress on this. Trying to use the tcl/tk from Apple or homebrew was a dead end. They're both using CoreGraphics, whereas tkgate is strictly X11 - i.e., completely incompatible.

Building tcl and tk from source (with the --with-x option in case of tk) and building and linking tkgate against that did work, now I just need to package it up into a simple recipe, probably a Makefile.
