X11

Hey peeps,

question on installing X11.
I have found a few pages that describe the process:

>        ftp http://www.opendarwin.org/downloads/7.2.1/X11-x86.tar.bz2
>        cd /
>        tar -jxpf {path_to}/X11-x86.tar.bz2

The link, however, is to the file:
X11-x86.tar.tar
Is this normal?

I have downloaded it and tried the above stated tar command but it does
not work. I get EOF errors. I also notice that at the download folder the
size of the file is stated as 44.4 MB. Windows agrees with this during
download but at completion the file size varies around 29MB which is
unusual behaviour.

Any help would be appreciated.

Best Wishes,
David Walker
