Well sorry for the noise and answering myself (but it seems this pops up 
every now and then so might be good to write it up).

Thanks to Roman who gave me in IRC the right pointer to look further 
into network issues...

Well I should have recalled better, :) actually I *had* installed wicd 
replacing network-manager, eventually reinstalling it trying to get a 
wifi connection to work (another story) and somehow 
/etc/network/interfaces was all commented including the loopback part:

auto lo
iface lo inet loopback

This means you have no localhot, which is what Pd tries to connect to, 
thus the hanging and failure.

Uncommenting those lines solved the problem.
