[OS X TeX] sh: realpath: command not found???

[Gray, Gary L]

I just tried to open the documentation for xcolor in Terminal and I got this error:

ESM-Euler:~ gray$ texdoc xcolor
sh: realpath: command not found

I saw this discussed recently and I thought it had been fixed. I ran TeX Live Updater this morning, so my distribution should be up-to-date. I should add that the file did open. Should this still be happening?
