Some more fixes

I created a hello-world repo, put this in my `cargo-lite.conf`:

    deps = [
        ["--git", "http://github.com/bjz/gl-rs.git"]
    ,   ["--git", "http://github.com/bjz/glfw-rs.git"] # bjz so amaze?
    ]

    [build]
    crate_file = "src/main.rs"

typed `cargo-lite.py install`, saw a few failures and fixed them. Not sure whether my usage is correct or if the gl* repos have the right stuff in their cargo-lite.conf files.

In case these are genuine bugs, feel free to merge them :-).
