Nasty! That same problem has caused me loads of headaches in the past.

The root cause of the problem is that the build system considers 
omniidl to be an integral part of the system, rather than a stand-alone 
utility. You need to be able to build omniidl (and omkdepend) 
separately from the omniORB libraries.

Do you have any enthusiasm for attacking the makefiles to implement 
that change?
