Hi Rodney,

Unless you see a compelling reason not to, I think that I'll stick with the
current version of the instructions. The object is to have something simple
for unsophisticated users, and the current version of the troubleshooting
instructions are already a bit complicated.

Best,
 John

Hi Rodney,

I've added a section on "Mac OS X Trouble-shooting" to the Rcmdr
installation notes at
<http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-

notes.html>,

with explicit instructions on the recent problems experienced by

Sarah and

Mark. I'd appreciate it if you could take a look at this to see

whether the

instructions are clear. Also, are there other cases that I should

cover?

Thanks,
  John

Hi John:

It looks pretty good to me; lot's of useful info.  I see that you have
sudo chmod -R a+rX /usr/local
as has been suggested.  It definitely makes sense; why have
/usr/local if no one can actually do anything with it?  However,
we are doing a bit more than fixing this issue at hand.  What if you
said it this way?

Having confirmed the problem, you can change the file permissions in
/usr/local/lib by opening a terminal window on your Mac (Terminal.app
is
in the Applications Utilities folder) and entering the following
command
at the $ prompt in the terminal window:

         sudo chmod -R a+rX /usr/local/lib

     The operating system will ask you to supply your password to
execute this command.

File-permissions problems such as this may also occur
when you attempt to install other R packages.  In that case, you
might consider performing the same operation on the directories
/usr/local/bin and/or /usr/local/include.  Since there is not
much point having /usr/local if no one can actually use it, then
you might consider altering the entire /usr/local hierarchy:

         sudo chmod -R a+rX /usr/local


But, now we have traveled pretty far afield from just Rcmdr...
