[MACTCL] Can't configure ttk::style on OS X

[Kevin W. <kw...@co...>]

I'm having trouble configuring the background of a ttk::style on OSX 
10.5, using Tk 8.5.7. The code below should draw the custom ttk::entry 
style to blend in with the background of the toplevel (#b2b2b2). 
However, what I'm seeing is a thin strip of the default ttk::frame 
surrounding the entry, which stands out against the gray background of 
the toplevel in an unpleasant way. Am I doing something wrong in the 
code below?
