R help - Mar 2010 - Error loading R Commander with version 2.10.1 on MacOS 10.5 or 10.6

Dear R Commander experts,

I have now had multiple failures in loading R Commander with R version 2.10.1
(most recent one on the CRAN site) on a Mac running OS 10.5 or 10.6. The
installation of R Commander seems to proceed normally, but when I try to start
up R Commander, it never loads. It appears that it is loading the tcl/tk package
that is failing even though I have started up X11 in advance. Does anyone have
any experience with this? I know that one of my students encountered the same
problem, and I have experienced it on more than one machine - both PowerPC and
Intel-based. We are routinely running early versions of R and R Commander.

I would appreciate any clues.

Best regards,

Dear Dwight,

I've never observed this problem myself, and many people apparently run the
tcltk and Rcmdr packages with R 2.10.1 under Mac OS 10.6 without difficulty.
You can confirm that the problem is with tcltk by trying to load that
package independently of the Rcmdr: i.e., library(tcltk). 

Similar questions have been raised several times, however, on both r-help
and the r-mac-sig lists, including in the last week. The problem is probably
with your installation of Tcl/Tk. See, e.g., Rob Goedman's recent post to
r-help, and the following message from r-sig-mac, which tells you what to
do.: <https://stat.ethz.ch/pipermail/r-sig-mac/2010-January/007008.html>.

I hope this helps (please tell me and the list whether it does).

John
