It [looks like](https://stackoverflow.com/questions/1676743/why-would-file-put-contents-succeed-but-touch-fail) a permissions related issue. Check the `user:group` owner of all of the files in the `craft/app` folder and make sure that they are set to the same `user:group` that your PHP installation is running as.
