I'm forwardinf this mail to r-sig-mac as well as it is of common
interest I guess.

By default, .tgz is the extension for binary packages for R under OS X.

It could be of interest to be able to reproduce it. Can you give us
some reproducible small workspace and R.app error log?

not for Wìndows, but under windows tcltk is always available. But you
are right, it works.

I'm not sure how he can solve this problem since (but probably someone
here has hints).

we can add an option for that R.app prefs in fact but I'm not sure it
could work either as launching X11 is not syncronous anyway. Even if
R.app starts X11 for you, there's no guarantee that X11 is really
running at the moment R requires it.
