[R-SIG-Mac] install.packages default type change?

[Simon Urbanek]

I see many people have been busy making the points I had in mind, so  
just two quick add-ons:

Those are exactly the reasons why tcl/tk library and g77 are disabled  
in the installer by default, although we include them in the CRAN  
image - if you know what you're doing, you can enable it, if you  
don't - nothing to worry about.

Ideally we should supply Tcl/Tk private framework for R, such that it  
is entirely self-contained, but we could get into trouble with Tcl/Tk  
add-ons in some R packages and configure scripts. This setup is a  
temporary work-around anyway, because in the long run the CRAN binary  
should use Aqua Tcl/Tk and not depend on X11 (while still supporting  
it, of course).

Thank you all for contributing to the discussion - the arguments I  
presented in the first mail were just what we came up after some  
thinking about it, but we could be wrong, so it's good to hear what  
the users really want...

Cheers,
