The following methodology seems to work pretty well in my case:

Check out the pristine source TWICE into two local working copies.

One one working copy perform the complete build.

Against that working copy run a python script based on os.walk that
looks for
a. executable files
b. other generated files of interest
c. newly created directories.

for each a or b found, use the python subprocess module to invoke svn
propget on the mirror of that directory in the second working copy.
This is necessary because, svn update and svn commit do not work on a
directory tree containing unversioned directories. Check to make sure
that the object is not already in the properties, and if not, add it to
the list and save it with svn propset.

for each c found do the same and then remove it from the dir list that
is recursed into by os.walk. Also remove any .svn directories from
os.walk without any processing.

Now there should be a clean copy of the project ignoring everything that
needs to be ignored.

I can't help but think there ought to be an easier way, but hey, job
security and all that.
