Sounds like a good opportunity for the underused for/break/else 
construct:

######################################################
ignored_dirs = (
     r".\boost\include",
     )

if __name__ == "__main__":
     # Walk the directory tree rooted at 'source'
     for root, dirs, files in os.walk( source ):
	for dirname in ignored_dirs:
             # may need to normalize to root.lower()
             if dirname in root:
                 print 'Skipping', root
                 break
         else:
             CopyFiles( root, files, ".dll" )
