As I understand it, rxvt will first look for cygX11-6.dll, which is in
xorg-x11-bin-dlls, and only then for libX11.dll (which is in
XFree86-lib-compat).  The fact that it doesn't find cygX11-6.dll probably
indicates that you don't have /usr/X11R6/bin in your PATH.  However,
without the system information requested in the Cygwin problem reporting
guidelines at <http://cygwin.com/problems.html>, the above is just a

The answer to "which package should I install to get file A" almost always
involves the Cygwin package search page at <http://cygwin.com/packages>.
A search for "libX11.dll" there points to the XFree86-lib-compat package.
However, as I said, you probably just need to add /usr/X11R6/bin to your

One other point: rxvt has a Windows native mode, which doesn't require a
running X server.  You can invoke rxvt with "-display :0" to get the
Windows native mode (it uses libW11.dll, which comes with the rxvt
package, and doesn't need X installed).
