Weird DemoGame linking errors...

... another linux linking error....
does anybody have an idea what might be causing this?
Everything compiles fine but then I get this....
(this is a somewhat old HEAD version, like 4-5 months I think, but I couldnt find any difference in the files or the make file that might cause this...)
Thx for ANY help!!
