[bug] TypeError: expected pointer, got Int64

After just installing pyro4 using easy_install (IronPython on windows 7), I get:

$ cat pyro_test.py
import Pyro4
daemon=Pyro4.Daemon()
uri=daemon.register({'test':True})
print "Ready. Object uri =", uri
daemon.requestLoop()

$ ipy pyro_test.py
C:\Program Files (x86)\IronPython
2.7\lib\site-packages\Pyro4\core.py:1: UserWarning: HMAC_KEY not set,

Traceback (most recent call last):

TypeError: expected pointer, got Int64


Do I need to run a 64 or 32 bit version or something explicitly somehow?

Cheers,
