[omniORB] OmniORB 4.1 on Mac OS X - problem with bind()

We are transitioning from OmniORB 3.0.4 to 4.1 are having problems 
starting OmniORB 4.1 on Mac OS X. It starts OK on Windows (XP and Vista 
tested) and Linux.

The problem occurs after ORB initialisation, when we try to find the root 
POA. Inside OmniORB, it is failing to bind().

Error message from OmniORB: -
        Error: Unable to create an endpoint of this description:

The global "errno" is 49, which is EADDRNOTAVAIL (address not available).

Due to problems on Vista, we have disabled IPv6 for the moment. We did 
src:lib:omniORB:orbcore:dir.mk .

We are explicitly setting the endpoint, via "-ORBendPoint", because we 
need to control how the host name gets stored in IORs, as they will go 
persistently into a Name Service. In OmniORB 3.0.4, we used 
"-ORBpoa_iiop_name_port". The hope is that these are equivalent. Are they?

The problem occurs if the value of "-ORBendPoint" is the machine's IP (v4) 
address. It does *not* occur if the value is "localhost".

I'm out of ideas. Anyone got any suggestions?
