[omniORB] ImportError: No module named _embed

[zsth@bigfoot.com]

I have problem using embed example from omniORBpy-2.0. The example have 
been compiled without errors but when I run embed.py I get:

Traceback (most recent call last):
	File "./embed.py", line 8, in ?
	  import _embed
ImportError: No module named embed

Usual Python extension modules without CORBA are compiled and used 
without problems.

System:
Linux Red Hat 7.2
gcc-2.96
Python 2.2.2
omniORBpy-2.0
omniORB-4.0.0
PYTHONPATH=.:/usr/local/lib/python2.2:/usr/local/lib

What I do wrong?
Thank you in advance.
