ActionBarSherlock v3.4.2 build errors

Question

I've added ActionBarSherlock to an Android project in IntelliJ IDEA, and I'm seeing the following build errors

Everything in the IDE says I'm building against platform API 11, which I expected would include these styles, though looking in API 11 I can't see them.

What am I missing? Does ABS only work with a later Android platform version?
