[orca-list] Orca Master Startup Problems

[Robert Cole <rkcole72984 gmail com>]

Hello, everyone.

I have built the following packages from Git:
-atk
-at-spi2-core
-at-spi2-atk
-pyatspi2
-orca

When I start Orca, I do not hear the usual "Welcome to Orca" greeting. 
When I start Orca from a terminal, I receive these messages:

[This message is displayed several times.]
** (orca:18907): WARNING **: at-spi: Expected message signature au but 
got  at atspi-accessible.c line 672

** (orca:18907): WARNING **: AT-SPI: Error in GetItems, 
sender=org.freedesktop.DBus, error=The name :1.22 was not provided by 
any .service files

[This message is displayed several times.]
** (orca:18907): WARNING **: at-spi: Got no message at 
atspi-accessible.c line 672

I also receive this message when I try to open Orca's Preferences window.

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/orca/orca.py", line 1640, in 
showPreferencesGUI
    module.showPreferencesUI()
  File "/usr/lib/python2.7/dist-packages/orca/orca_gui_prefs.py", line 
3537, in showPreferencesUI
    orca_state.orcaOS.init()
  File "/usr/lib/python2.7/dist-packages/orca/orca_gui_prefs.py", line 
452, in init
    self._initGUIState()
  File "/usr/lib/python2.7/dist-packages/orca/orca_gui_prefs.py", line 
1702, in _initGUIState
    prefs["enableLockingKeys"])
KeyError: 'enableLockingKeys'

Did I build something incorrectly, or did I come across a bug?

If I built somethign incorrectly, can I simply go into the directories 
for atk, at-spi2-core, etc and run sudo make uninstall to remove 
everything and start from scratch?

I apologize for my ignorance in all of this.
