When wine needs libtxc_dxtn it should check for its presence and when it is missing it should write a message, which mentiones libtxc_dxtn. Such a message would have saved me some time. Additionally the wine packages (from the Distibutions) should contain a dependency on libtxc_dxtn. Maybe somebody should tell this to the package maintainers.
It's not Wine that depends on libtxc_dxtn, but the graphics driver. Current Wine version have an improved error message that makes it a bit more clear that the problem is missing S3TC support, but that too is new in wine-1.5.9.
