py-sip broken?

Hello,

When trying to install py-sip through port, it fails to fetch the source 
file sip-4.4.2.tar.gz.

There is a newer version of sip available from the creators, sip-4.4.5, 
which unfortunately fails to compile on my machine.

I managed to find a copy of the 4.4.2 sources on a different mirror, but 
I'm not sure if I can easily get port to fetch the sources
from there instead?  It would be quite nice to have py-sip maintained 
through port.

Cheers,
Damian
