python 2.5 => alacarte and py-avahi

[Franz Klammer]

After upgrading to python 2.5 i cant't compile py-avahi and alacarte.
i had to change something in the ports to make it build again.
below the diff i made for the port. maybe it's usable.

i don't use send-pr because i use marcusmerge and not the ports
from the main ports tree.
