[gentoo-user] ati-drivers-8.552-r1 is blocking xorg-server

[Nikos Chantziaras]

I can't figure out how to fix this.  emerge ati-drivers gives this:
[ebuild  N    ] x11-drivers/ati-drivers-8.552-r1  USE="acpi -debug" 
74,042 kB
[blocks B     ] x11-drivers/ati-drivers (is blocking
x11-base/xorg-server-1.5.2)

I'm trying to modify the ebuild:

/usr/portage/x11-drivers/ati-drivers/ati-drivers-8.552-r1.ebuild

(in my local overlay of course) but I don't see where the block occurs. 
 Can anyone help?  The dependencies are the following and I can't 
figure out why they're blocking xorg-server-1.5.2:
