I understand this is an xcode warning/error, however, it happens when I try to run gitk --all
from the command line.

Running gitk with a new version of tcl-tk seems to solve this problem (tested with Mac OS X 10.8.4). If you have Homebrew installed, the following should work:
brew install tcl-tk
alias gitk='"$(brew --prefix tcl-tk)/bin/wish" "$(which gitk)"'
After restarting your terminal, you should be able to run gitk normally without seeing any "CFURLCopyResourcePropertyForKey" errors.
