[R-SIG-Mac] Unable to load Rcmdr with R 3.0.1 on a Mac OS X 10.8.3

[Simon Urbanek]

Sarah,

errno=13 is "permission denied" so it seems like your system's access control is somewhat misconfigured. Did you try "Repair Disk Permissions" in "Disk Utility"?

If that doesn't help please send us the output of the following R command:

system("ls -ld /usr/local /usr/local/lib /usr/local/lib/libtcl*")

Thanks,
Simon
