It means your TeXLive installation is missing the "cancel" package. You 
can install the texlive-latex-extra package, which is a bundle that 
includes cancel, or you can try running the TeX Live manager program 
(tlmgr) and using that to install just cancel. Once you've installed it, 
retry displaying the document.
