I remember I used to do something similair with libXdpms.a to make avifile happy,
now I did:
	cd /usr/X11R6
	cc -shared -o libXxf86dga.so.0.0 libXxf86dga.a
        ln -sf libXxf86dga.so.0.0 libXxf86dga.so.0

And the plugin compiled. It works "properly" (displays something), locks xmms
permanently, though. Sound stops working, I can see only video. I can't even close
preferences menu.

When additionally I tried doing:
	ln -s sf libXxf86dga.so.0 libXxf86dga.so, the package does not want to compile:

When I built shared version of libXxf86vm (with so.0 -> so link) I get even more undefined references:

I don't understand it. I'm going to recompile SDL with shared versions of libXxf86{dga,vm} and see if this changes anything.
