Ok, I now understand the rationale for doing it that way. You bring up an
interesting point. However, having to run the configure script is 
non-intuitive. Of the several ideas that I can think of, I believe your 
idea 
(below) of a new script is the best; that way it will be minimally 
disruptive to the 
current process followed to create the distribution itself.

Yes, that would definitely be a good start. Having a script named 
appropriately 
(something along the lines of update_sources) that does apply the specific 
patches would
be helpful. Also the same script can be invoked from configure. 
Additionally, this
needs to be well documented in the README.txt file so that someone else 
does not run into
the same caveats in the future. Thanks for your help with this!
