The file to be installed in usr/bin/bzr does not specify a specific version of python either in its installed path nor in its text.  Such a file cannot be analyzed for dependencies since the version of python it will be used with is unknown.  The text of the file is here: /home/bleonard/proto_install/usr/bin/bzr.
