You can't. The only things that trigger a recompile are the things you already know - version number change - USE flag change - mask change None of those things has occurred in your scenario, so a recompile will not happen. This is by design and you should leave it this way. I suppose you *could* examine the version number in the CVS checkout, compare it to the last built version and make a decision based on that. Two problems: 1. Such version numbers cannot universally be relied upon 2. Portage does not currently store this information in any way that I have found, so you will need to patch portage. It's best to just always recompile everything, which is what you do when you work with CVS code manually. I also asked the same question in the past - about e17 - the above is my conclusions. -- alan dot mckinnon at gmail dot com
