Compile error

[avpdiver]

Hi!
I have tried to build small 'helloworld' code with gl-rs dependency (https://github.com/bjz/gl-rs) and get error:
Compiling rust-xml v0.1.0 (https://github.com/netvl/rust-xml#d6c57380)
src\namespace.rs:67:36: 67:45 error: type bool does not implement any method in scope named is_none
src\namespace.rs:67 self.0.insert(prefix, uri).is_none()
error: aborting due to previous error
Could not compile rust-xml.

I am using Rust version 0.13.0-nightly (0a5e7f359 2014-11-03 23:16:55 +0000) on Windows 8.1

Your compiler is not up-to-date.
In the version you have insert returns a bool, but in the nightlies it returns an Option.
