First of all, omniORBpy 2.7 isn't guaranteed to work with omniORB 4.0.6
-- you should use omniORB 4.0.7.

The configure doesn't always work if you install omniORBpy with a
different prefix to omniORB itself. It's better not to use
--with-omniorb but rather to configure both omniORB and omniORBpy with
the same --prefix.

You can only avoid setting PYTHONPATH if you install omniORBpy to the
same prefix that Python itself uses. With any other prefix, you need to

It sounds like you are trying to set PYTHONPATH to be the source
location of omniORBpy. That's wrong. You need to install omniORBpy, then
set PYTHONPATH to the install location. If you don't give configure a
--prefix, then it uses /usr/local, meaning that you need to set
PYTHONPATH to /usr/local/lib/pythonX.Y/site-packages replacing X.Y with
whatever Python version you have.
