R help - May 2007 - Error in X11(display, width, height, pointsize, if (is.null(gamma)) 1 else gamma, : invalid 'width' or 'height'

Hey, I've been using R for several years and I just upgraded my system and
all
of a sudden I'm getting the above message.  Here it is again

Error in X11(display, width, height, pointsize, if (is.null(gamma)) 1 else 
gamma,  :
        invalid 'width' or 'height'

I get it on two computers, one on AMD64 and one on x86, both running Gentoo 
unstable.  If I do ?x11 and type in the default usage thingy, it works 
perfectly well.  I.E.:

     X11(display = "", width = 7, height = 7, pointsize = 12,
         gamma = getOption("gamma"), colortype =
getOption("X11colortype"),
         maxcubesize = 256, bg = "transparent", canvas =
"white",
         fonts = getOption("X11fonts"), xpos = NA, ypos = NA)
 
works.  Similarly, calling x11 with width and height of 7 works fine.  The 
locale of my computer is UTF8 but that hasn't changed since the upgrade and 
it was working well before. Does anyone know what might be going on?  Any 
help is appreciated, thanks!  I've tried searching both the Gentoo and R 
help.
