kill ring and system clipboard

[Mark Stoelinga]

Hello,

I know there are many posts on this topic on various forums, and lots of 
advice, but I've read and tried all of it with no success.

Basically, I want my emacs kill-ring contents to be available in my system 
clipboard on my mac, but I can't get it to work.

My setup:

I have a MacBook laptop, running Snow Leopard (OSX 10.6.2).  I use a mac 
terminal to ssh into a Linux cluster that is running Gnu Linux (not sure of the 
version).  I'm also running the XQuartz X11 emulator on my MacBook.  When in 
the terminal, loogged into the Linux cluster, I run "emacs" (which is Gnus 
Emacs version 21.3.1).  This successfully opens emacs in an X11 window (via 
XQuartz) on my mac desktop.  This all works splendidly.  And I generally can 
get anything from any mac application or other X application INTO my Emacs kill 
ring through either a mac copy (Command-v) or a X11 middle-mouse copy.

My problem:

However, what I have never been able to do is get the emacs kill ring contents 
to go into my mac system clipboard.  The closest I've managed to come is 
issuing the emacs command "META-X set-variable RET x-select-enable-clipboard 
RET t".  This seems to sync up the kill ring contents with the system 
clipboard, BUT now I can no longer put anything new into the kill ring from 
within emacs.  If I kill a line, the line gets deleted but whatever was in the 
kill ring before remains in it.  I've also tried, instead, using the emacs 
command "clipboard-kill-ring-save", but this does not have the desired effect 
of forcing the kill ring contents into the system clipboard.  The mac system 
clipboard is uneffected.

Any new advice would be very appreciated!
