need libX11.so

Can somone e-mail me libX11.so and tell me where it goes? I gess for what ever resion it never made its way into xdarwin version of x-windows. I need it to compile stuff

XDarwin does not contain X11, so you probably don't have an X server installed. Install XFree86.

Xdarwin the X-windows disabution! www.xdarwin.org
I do have it installed.
