So let's move to R-devel.

It has been possible on Unix and Windows for a while, but it seems is not 
yet implemented on MacOS X (although I submitted the code needed). 
However, it is only the default on the Windows GUI and not for any 
command-line version of install.packages().  People have from time to time 
suggested changing the default, but the dependency tree can get rather 
large and some people do have slow and expensive connections.

I think a bundle is still a better idea.  Apart from on MacOS X we need 
some education about how to use the power of *.packages (and we need to 
get the MacOS versions in place).  For example, bundle components show up 
with the dialog-based installation lists.
