[R-SIG-Mac] Error loading packages

[Johanna Elsensohn]

Hello,
I'm not having any luck loading two packages, ggplot2 and psych so I'm not
sure if this is Mac specific or Rapp specific. When trying to load the
packages, I get the below error messages, highlighted in bold. I have tried
installing and loading the package asked for (in this case 'munsell'), but
the same error message will appear, with a new/different package name. I
have uninstalled and reinstalled R and the packages themselves, and from
several different mirrors. I had the same issue on R v3.2.1. I'm not sure
what else to try, or how many other packages are affected. Thanks for any
help you can give me. My script and session info are below.

For R "Fire Safety", v3.2.2.
