Dear David,

it was when I tried to install an R package tailored to my setup (so after changing the source). So that was certainly something only affecting my setup. I'm quite sure it would not have inferred with the PATH I now have (after changing it as mentioned earlier), only with the one I had before (the default PATH):
bash-3.2$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin:/opt/local/bin:/opt/local/sbin:/usr/local/texlive/2011/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/texbin:/usr/local/texlive/2011/bin:/usr/texbin:/usr/local/texlive/2011/bin

I guess you refer to here: http://www.emacswiki.org/emacs/EmacsApp

But that requires (?) to adjust it manually everytime PATH changes (and sometimes one does not know -- some program is appending things to PATH [afaik]).

I guess what's more important is the question: What are the differences between a shell opened with M-x shell from within Aquamacs to the shell opened via Terminal.app? Only environment variables? Anything more? Because these are the things one should keep in mind when working in a shell opened from within Aquamacs.

Cheers,

Marius
