The problem is that it doesn't know that the path TUI is important when 
you give it a mainprogram; mainprogram can be any path.  When it does 
modulefinder on your mainprogram, it sees it as __main__, not as 
TUI.Main, as it should.

If you follow the standard unix way of doing scripts, which is writing a 
script "tui" that imports TUI.Main and calls whatever needs to be called, 
then everything will work just fine.  That's what mainprogram is.
