Template mixin problem

[Olli Aalto]

I already posed this question on the #D channel, but here's for the rest 
of you.

Here's the error:

oaalto-desktop Projects/workspace/MixinTest> dsss build
mixins/main.d => mixin_test
mixins/HelloWorld.d(7): mixin is not defined
mixins/HelloWorld.d(8): mixin 
mixins.HelloWorld.HelloWorld.HelloSpeaker!() error instantiating
mixins/HelloWorld.d(7): mixin is not defined
mixins/HelloWorld.d(8): mixin 
mixins.HelloWorld.HelloWorld.HelloSpeaker!() error instantiating
Command /home/oaalto/D/dsss/bin/rebuild returned with code 256, aborting.
Error: Command failed, aborting.

Any ideas what's going wrong?
