basic docs example incorrect moving from 0.11.0 to 0.11.1

[Alissa Pajer]

In version `0.11.0` the following works. But in version `0.11.1` I get `NoSuchMethodError`. I'm seeing this same error in the docs example as well as in my own code.

This example is from the docs here: http://dispatch.databinder.net/Dispatch.html. What is the correct way to perform this example in dispatch version `0.11.1`?

```
import dispatch._, Defaults._
val svc = url("http://api.hostip.info/country.php")
val country = Http(svc OK as.String)
```

And the error:

```
scala> val country = Http(svc OK as.String)
java.lang.NoSuchMethodError: org.jboss.netty.handler.codec.http.HttpHeaders.set(Ljava/lang/String;Ljava/lang/Object;)Lorg/jboss/netty/handler/codec/http/HttpHeaders;

```

Update: Wiped my .ivy2 cache and ran `sbt clean`, just in case. But still have the same problem.

Hi Alissa, I'm not seeing that when I run the example code. Are you
testing with an independent project, in a clean directory where you've
run this?

echo 'libraryDependencies +=
"net.databinder.dispatch" %% "dispatch-core" % "0.11.1"' > build.sbt

Just guessing from the stack trace, it might be that you have dispatch
in combination with some other build instructions that might be
requesting a different version of netty.

Awesome, thank you!! I indeed was not in an independent project and I do have other dependencies depending on netty.

I upgraded everything to its latest version in my build.sbt, and now I can run the demo example again!

Thanks :)

No problem, glad you got it figured out. :-)
