Thank you all for the feedback!
I do remember now that I had to upgrade to python26 a couple of weeks ago and said to myself not to forget to upgrade all the other relevant ports, but seems that I forgot about that
The interesting part of this is that I didn't get any errors while using the 'outdated' python dependent ports.
After upgrading the ports to python26 everything is fine - x11/gnome-desktop is building just fine, that's a relief
But the issue with rxvt-unicode is still relevant - don't know why... Perhaps somethings else I'm missing here..
Regards,

P.S.: Hey, where did the "Thanks" button go? I don't see it anymore..
