it is currenty not possible to run the realtime module under Windows.

What you described is a good way of developing Etherlab Software. We 
never tried running "setup_etherlab" under Windows because we only work 
under Linux. So we would be happy if you send your modifications to the 
"setup_etherlab" m-file and the "makefile" to patch it to a future 
Etherlab-Version.
The missing symbols is because you use an "new" Matlab/Simulink Version.
Up to "matlab2006b" Etherlab should we running fine, but the 2007 
Edition has references to this symbols. We just didn't have time to fix 
the problem for the current Matlab release, so if you fix it and provide 
a patch we would be very happy.

Best regards

Wilhelm Hagemeister.
