*sigh* again, it is not 'masked'. Masked means 'package.mask entry' in gentoo- user speak. Masked in package.mask means 'unfit for human consumption'. Masked by unstable keyword means exactly that: the package is marked as unstable at the moment. One of your many packages installed depends on an unstable package. If you only have stable packages installed, you just hit a bug. But if you have unstable packages installed, this happens all the time. Add jpeg7 and -compat to your package.keywords file and go on. Another reason, why mixing trees is a bad idea...
