It would be nice to integrate this with speech-dispatcher, see http://www.freebsoft.org/speechd. > (Let me know if someone would like to help > to put it into Ubuntu's repository).

You probably need to talk to the upstream at-spi maintainers, as that is likely where the support needs to be added, since Orca uses at-spi to deal with all of its input snooping, to determine what keystrokes have been pressed etc. I suggest you mail the GNOME accessibility development mailing list at gnome-accessibility-de...@gnome.org to start a dialog.

The issues you raise are common amongst people who end up having more than one copy of Orca, and other libraries on the system. As I suggested above, you should install all of orca's build dependencies before you try to build it.
