Not really a Tcl user, except incidentally. (Who knows what the future holds, though?)
Currently (24Sep12) just trying to bring up (on MacOS) a Python application that uses Tk and Tile in its GUI. I got here from a Google search, specifically to the page Tile and BLT together on MacOS X, which led me to figure out a way to resolve my problem building Tile -- which I then documented in an update to the same page.
