Folks,
 I just upgraded my Mac to Mountain Lion and on running R.app I get the following message:

mach_override: some instructions unknown! Need to update mach_override.c
err = f8000001 /Volumes/Haxdisk/Projects/DefaultFolderX/DFCarbonPatch/../../Libraries/mach_star-1.2-intel-0.3/mach_override/mach_override.c:215
err = f8000001 /Volumes/Haxdisk/Projects/DefaultFolderX/DFCarbonPatch/../../Libraries/mach_star-1.2-intel-0.3/mach_override/mach_override.c:228
err = f8000001 /Volumes/Haxdisk/Projects/DefaultFolderX/DFCarbonPatch/../../Libraries/mach_star-1.2-intel-0.3/mach_override/mach_override.c:234
err = f8000001 /Volumes/Haxdisk/Projects/DefaultFolderX/DFCarbonPatch/../../Libraries/mach_star-1.2-intel-0.3/mach_override/mach_override.c:248
err = f8000001 /Volumes/Haxdisk/Projects/DefaultFolderX/DFCarbonPatch/../../Libraries/mach_star-1.2-intel-0.3/mach_override/mach_override.c:253


Note that I have loaded no packages nor run anything else on start-up.

Here is my session info:

> sessionInfo()
R version 2.15.1 (2012-06-22)
Platform: i386-apple-darwin9.8.0/i386 (32-bit)

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
[1] tools_2.15.1

Does this relate to my upgrade or something else? Is there a way to fix this.

One thing that I have noticed (after updating all my installed packages) is that much of ggplot2 will not work for me anymore.

Thanks for your time,
KW
