I've also got the ORB building in a cross environment.  The crux of the matter was defining HOSTTOOL=yes in the GNUmakefile's for tools that run on the host, and then including either the correct platform file (either host or target) in config.mk.  Along the way, I ran into the same problems you are having.  I had the gatekeeper disabled, but that's not your current problem, and probably won't be a problem at all.

I would try getting eg1 working first, and only then worry about eg2.  These are the steps I followed to get things working.  Basically, once you can do a 

$ ping <hostname>

to ping yourself, and it works, eg1 and eg2 should work.

1. Assign a hostname using the hostname command like this:

$ hostname <hostname>

2. Make sure there is an entry in /etc/hosts for <hostname>

3. Make sure the loopback interface exists and is running.  Check this by running ifconfig

If the loopback interface either doesn't exist, or isn't running, do this:

# ifconfig lo 127.0.0.1 up

>From here, ping <hostname> should work.

Good luck.
