  Certainly:

skx at itchy:~$ dpkg -l "*xen*"

  Whoah, what a big list!

  OK.

  I've made that change and now recieve this:

skx at itchy:/usr/lib/xen-3.0-unstable-1$ sudo /etc/init.d/xend restart
Restarting XEN control daemon: xendTraceback (most recent call last):
  File "/usr/lib/xen-3.0-unstable-1/bin/xend", line 118, in ?
    sys.exit(main())
  File "/usr/lib/xen-3.0-unstable-1/bin/xend", line 99, in main
    start_consoled()
  File "/usr/lib/xen-3.0-unstable-1/bin/xend", line 85, in start_consoled
    os.execvp(sys.path[0] + '/xenconsoled', ['xenconsoled'])
  File "/usr/lib/python2.4/os.py", line 341, in execvp
    _execvpe(file, args)
  File "/usr/lib/python2.4/os.py", line 367, in _execvpe
    func(file, *argrest)
OSError: [Errno 2] No such file or directory
 failed!


  Adding a print to the code:

  sys.path[0] = '%s/../lib/python' % sys.path[0]
  print sys.path[0]

  I see:
/usr/lib/xen-3.0-unstable-1/bin/../lib/python

  That seems to be correct since my xc.so is at
 /usr/lib/xen-3.0-unstable-1/lib/python/xen/lowlevel/xc.so
