R help - Apr 2012 - X11 display problem

Hi,
I run R on a unix server and login from a Mac with ssh -X. When I want to run a
graphics function like hist, I get the following x11 message:

Error in X11(d$display, d$width, d$height, d$pointsize, d$gamma, d$colortype,
 : 
  unable to start device X11cairo
In addition: Warning message:
In function (display = "", width, height, pointsize, gamma, bg,  :
  unable to open connection to X11 display ''

Do I need any library like cairo installed on my local Mac? 

I also set LC_CTYPE="en_US.UTF-8" in my profile

Cheers,

Carol

I use ssh -Y in this situation.

You can test with other X client applications, such as xclock. Try running
xclock after your login. If you get the same "unable to open" message
then
it's not an R problem.
