I don't know about PDB, but you'll see the permissions problem if gdbserver-xen is not run as root.

I gave pdb a whilr for good measure and it is similarly not working:
[root@cirrus libxendebug]# pdb 9999
ERROR: Could not obtain handle on privileged command interface (2 = No
such file or directory)
(pdb) error opening xc interface: 2 (No such file or directory)
ERROR: do_evtchn_op: HYPERVISOR_event_channel_op failed: -1
(pdb) evtchn_bind_virq error!
failure: [evtchn_bind_virq error]

This with a freshly built libxendbug and pdb.
