tcltk is a base package, distributed with R.

It may be as simple as starting X windows before you try to load tcltk.
On OSX, X isn't normally running, but the tcltk implementation used by R
requires it. Try clicking on the X in the menu bar if you're using
R.app, or start R from an X terminal if you're used to the command line
version.
If that's not sufficient, I'd suggest asking on the R-sig-mac list,
where you'll find the real Mac experts, not just occasional users like me.

I'm not sure how Apple version numbers work, but that one looks old: it
may be that R 2.6.2 doesn't support it any more.
