I don't think we have seen such a misconfigured system before.  What is 
`Linux' here?

I doubt it, unless erroneously is `fine'.

R works well on several Linux x86_64, e.g. FC3.  I get

gcc -shared -L/usr/local/lib -o R_X11.so  dataentry.lo devX11.lo 
rotated.lo rbitmap.lo  -lSM -lICE -L/usr/X11R6/lib64 -lX11  -ljpeg -lpng -lz

(on R-devel, where the unnecessary -lncurses -lm are skipped).

Where did /usr/X11R6/lib come from?   Probably by configure calling xmkmf, 
and likely that is broken on your `Linux'.   Please take a close look at 
the configure output.  I see in config.log:

configure:34402: checking for X
configure:34640: result: libraries /usr/X11R6/lib64, headers /usr/X11R6/include


Setting --x-libraries should work, but you do need to delete the cache 
first.
