Ah, no.  Standard configure switches are used.  Debian (inherited by Ubuntu)
has a post-installation script for Python packages which create the .py
symlinks and do the byte-compilation.  The big win here is that much of this
can go away now (and in fact there are modifications to this post-installation
script already).
