See below.

R GUI has nothing to do with the shell - that's a whole another story.  
I wasn't suggesting you set that PATH permanently at all - it is only  
meant for compiling things against GTK+ if you want to (it overrides  
some system commands, so it's not a good idea to do that permanently).  
Also I was referring to R CMD INSTALL or similar method (you didn't  
mention you are using the GUI at all). If you want to use the R.app  
GUI for this, clearly, you have to set it in R, e.g.:

Sys.setenv(PATH=paste("/Library/Frameworks/GTK+.framework/Resources/ 
bin",Sys.getenv("PATH"),sep=':'))


Now, this has nothing to do with your original question, but R.app is  
a Cocoa application so it is started by  launchd (via LaunchServices)  
- it is not started from the shell, so all .profile/.bash/etc. are  
irrelevant here. You can, however, set custom environment variables  
using Environment.plist (see Apple QA1067 - it was also discussed on  
this list several times as you'll see if you look at the archives).

I don't know what you are referring to, all US mirrors have RGtk2  
AFAICS and in fact they have rattle as well, see
http://cran.us.r-project.org/bin/macosx/universal/contrib/2.8/

You'll have to supply more details (at the very least sessionInfo() as  
we kindly ask you in the posting guide) if you want more help.

It is a good practice to not merge multiple entirely unrelated issues  
into one post. See archives for the discussion on <Cmd><Enter> and  
newline (feel free to comment) and for the former, please be more  
specific as of what it should do - "function definition" as a very  
vague term and if you want the GUI to find the function definition in  
the sources, then sure, contributed patches are highly welcome (in a  
separate thread, please).

Cheers,
Simon
