question about compile X11R7.1

[falls huang]

Hello!

    I downloaded X11R7.1 from
http://xorg.freedesktop.org/releases/X11R7.1/src/everything/  , and
started to compile it myself.  I found X11R7.1 depends on xtans ,
but I couldn't find xtrans in
http://xorg.freedesktop.org/releases/X11R7.1/ .  Where can I find
xtrans ?

Thanks in advance.
