Since Tix wasn't being added automatically (see my first Tracker item), I tried to add support with the Data Folder feature.
If I supply a destination path of 'tcl/tix8.4', PyBuilder/py2exe hangs without completing. Looking into the build folder I see a binary file in 'tcl' instead of a folder.
If I supply a destination path of 'tcl/tix8.4/', it still hangs in PyBuilder/py2exe. However it appears to have copied the files (but not subfolders I beleive) the the build folder. However the Binary folder doesn't have the 'tix8.4' folder.
I also tried doing each subfolder one at a time (so it wouldn't have to copy subfolders) but had essentially the same results.
Note that the Data File feature did work to add the tix84.dll file to the 'DLLs/tix84.dll' destination path.
This is with PyBuilder 0.3 and Python 2.5.2 running on Win XP SP2.
