body: <p>I set a simple tweak using theos following the tutorial <a href="http://brandontreb.com/beginning-jailbroken-ios-development-your-first-tweak/" rel="nofollow">here</a>. However when I run make with the headers from <a href="https://github.com/Fr0stDev/SpringBoard-iOS5-Headers" rel="nofollow">here</a>, I get</p>
