As you do not have capabilities for cairo nor X11, read ?png, e.g.

     type: character string, one of ‘"Xlib"’ or ‘"quartz"’ (some OS X
           builds) or ‘"cairo"’.  The latter will only be available if
           the system was compiled with support for cairo - otherwise
           ‘"Xlib"’ will be used.  The default is set by
           ‘getOption("bitmapType")’ - the ‘out of the box’ default is
           ‘"quartz"’ or ‘"cairo"’ where available, otherwise ‘"Xlib"’.

      R can be compiled without support for some or all of the types for
      each of these devices: this will be reported if you attempt to use
      them on a system where they are not supported.  For ‘type =
      "Xlib"’ they may not be usable unless the X11 display is available
      to the owner of the R process.

So, the only type available to you appears to be "Xlib", and that 
process does not have access to an X server.

The strongly recommended solution is to get cairographics working: see
