Graphics pipe error with current build-bot Mac build?

I just installed the current Panda3D build bot Mac build over a fresh Mac OS X install and got this error when I try to use sample programs:

ppython /Developer/Examples/Panda3D/Motion-Trails/

DirectStart: Starting the game.
:display(warning): Unable to load: dlopen(/Developer/Panda3D/lib/libpandagl.dylib, 10): Symbol not found: __Z18init_libosxdisplayv
  Referenced from: /Developer/Panda3D/lib/libpandagl.dylib
  Expected in: dynamic lookup

Known pipe types:
(all display modules loaded.)

StandardError: No graphics pipe is available!
Your Config.prc file must name at least one valid panda display
library via load-display or aux-display.

I have no idea what that Z18init thing is. Before submitting a bug I wanted to ask if this problem is known.

Mac OS X.8.2
mid 2007 MacBook Pro
XQuartz 2.7.4 (still required!)
Cg Tools 3.1 April 2012

The same error with january builds. Use 1.8 to avoid

Sorry that it took me so long to get to this. I’ve checked in a fix and the latest devel build should fix this.
