Just for the records, below question arose in a different thread. Pablo had a problem installing tcltk (and Rcmdr) on R2.15.2 on OSX 10.7.5.

Turns out on his system X11 did not work with R.app. After replacing X11 with XQuartz (  http://support.apple.com/kb/HT5293 ), Pablo was able to get Rcmdr working with help from John (see below). The updated version (>Rcmdr 1.9.5) is not yet on R-Forge as of this morning, as John mentioned.
