The port was broken by the automatic REINPLACE_CMD conversion, as it used
Perl's syntax for replacements. It was officially marked BROKEN by kris
this May. This commit fixes the replacements and removes three directories,
which are created by the py-xml port, from the pkg-plist.
The maintainer did not react to the breakage in a very long time, so I
take the liberty of fixing the port without waiting for too much longer.
