X11

Dear discuss,

subsequent to my previous post (1/03/05), I have installed OD 7.2.1 on my
i386.
I now want to install XFree86 and then AfterStep but have a few problems.

I looked through the list of available ports at OpenDarwin (
http://darwinports.opendarwin.org/ports/?by=cat&substr=x11 ) to find an X11
but only found 2 versions of XFree86 available and a reference to the
XFree86 website.
I went there and was intending to get XFree86 from
http://ftp.xfree86.org/pub/XFree86/4.3.0/binaries/ as this is the latest 386
binary for OD I found on their site.
I noticed, however, that their are a couple of downloads available at
http://www.opendarwin.org/downloads/7.2.1/ that may appropriate.
The filenames and links are:
http://www.opendarwin.org/downloads/7.2.1/X11-x86.tar.bz2
http://www.opendarwin.org/downloads/7.2.1/org.opendarwin.X11-7.2.1-1.i386.rpm
Can anyone tell me if these files are XFree86 or not? My guess is they are
not and that they are probably ports of x11 for OD and therefore won't have
twm.
Can someone tell me if they are binaries? How would I tell? Which one is
appropriate for me to install?

I understand that these questions are pretty basic but that's my level :].
If you feel inclined to answer could you please answer in plain english and
then dumb it down a bit...

I realise that the description of the 'Discuss' list is "Discussion about
the direction and infrastructure of OpenDarwin" but none of the other lists
seem appropriate.
If you could point me to some good noob resources and a forum/list I might
leave you alone...

Best Wishes,
