OK, that might indicate that TkMacOSXUseAntialiasedText may need to be
promoted from a module-scoped symbol (i.e. utterly Tk-internal) to Tk's
internal stubs table. No big deal if the symbol is needed.

The module scope stuff is about trying to clean up the Tcl/Tk core so
that symbols are exactly as widely available as they need to be. This
really stems from the fact that its introducing a concept that
traditional Unix linkers didn't support; symbol visibility wider than
the file level but less than the application level.
