I did it and I use it without any problems. All the tests included in [make
test] run without error.
I reported the Hurd poblem to the R developers, and got the following answer:

Just a quick thought....

Rather than being a problem with X11, it looks like it may be a
problem associated with dlopen() when the R_X11.so library is
explicitly loaded during the initialization. Basically, that `library'
(R_X11.so) has to resolve all of the symbols to which it refers, and
many of them are in the R executable (R.bin). Perhaps the linking and
loading mechanisms in Hurd do not export these symbols from the
application in a way that shared libraries can find them.  Or it may
be as simple as the flag passed to dlopen() not being RTLD_GLOBAL
(although that shouldn't matter).

This probably says more to you than to me.
One thing is important: who moves next?
