Client install fails on my MacOSX v10.8.5

Hi,

I cannot install the client build drivers from 22 Aug on my Mac OSX box.
Its finding my Raspi Hub okay but then driver installation fails when clicking the usb device.

Heres the relevant console log entries. Seems something like kernel header issue on the build process maybe?
Also tried rebooting and installing again as recommended multiple times but same error all the way.

Any Idea what I could try?

Console:
