The www/py-webware port (I'm the maintainer of it) uses a uid which is reserved for the net/quagga port. The attached patch, which should be applied with $PORTSDIR as current directory, sets the uid and the gid for the port to 108. These settings are not used yet, according to http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/dads-uid.html

Fix: Patch, to be applied from $PORTSDIR:

- IGNORE=               uses uid registered to quagga.
-
  BUILD_DEPENDS=        ${PYTHON_CMD}:${PORTSDIR}/lang/python
  RUN_DEPENDS=  ${PYTHON_SITELIBDIR}/mx/DateTime:${PORTSDIR}/lang/py-mx-base
