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...
