installing 6.7.99.1-2

[Jack Tanner]

I'd like to install and test the 6.7.99.1-2 pre-releases ago recently 
announced.

I run setup, find a mirror that has the 6.7.99.1-2 files, and then click 
    in the New column for xorg-x11-base until it gets to 6.7.99.1-2.

I want to upgrade xorg-x11-bin at the same, so I try to pick 6.7.99.1-2 
in for that package as well, but when I do that, xorg-x11-base reverts 
to Keep!

It seems like the dependencies among packages are funny. xorg-x11-lndir 
also resets some of my selections.
