 R will have X11 capabilities if you have the X11 _binary_ library
installed. To compile a package from source that needs to link with
the X11 library you need the development headers. They come in another
package.

 From the command line, do:

 sudo apt-get install libx11-dev

and that should pull them from the Ubuntu repository. You'll need the
root password for this.

 It's possible you may need some other development headers once you
get past the X11 problem!
