The missing reference R_InputHandlers is declared in the
$RHOME/src/include/R_ext/eventloop.h file, and I believe is compiled
into the library R_X11 (with some extension).  You don't seem to have
that in the list of libraries:

I don't know what you'll need to do to fix this, since I'm using
Windows, so none of this stuff happens there, and I could be
completely wrong about it.
