Holmes] Neil: the problem before was an incomplete understanding of how the USE Flags worked, and a mis-understanding of some advice that I was given. The procedure that I used last time was: rebuild the kernel Set use to USE="-*" Emerge -e world
I broke my system this way once...
That procedure with the USE flags is what killed me. What I should have done -- it now appears was to set use to blank (or comment it out) and allow it to use the base flags from the profile. But trying to recompile from base with all use flags specifically excluded is what began to break stuff
When you leave the USE empty or commented, portage gets default set to compile, this set has options that work most of the time. But when you set it to "-*", it simply disable all optional (and sometimes most necessary) stuff for all packages. So, unless you have the time to take a full "emerge -epv" list, join it with a "emerge -epv system", put "-*" at USE and start setting each and every package at package.use or putting global configs at the USE flag, its not a good way to do it (but you would get a super fine tuned gentoo system, after a few days of configuration and a few weeks of debuging like: "why this package don't work, oh, it was because that other package needed that flag"), you should leave it empty and add/remove flags after the system is up and after knowing exactly what you'll be doying with that package. Gentoo is so flexible that it becomes a little difficult to configure (and I mean fine tunning at maximum) sometimes. For my desktops, I just leave USE empty. -- Daniel da Veiga Computer Operator - RS - Brazil -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCM/IT/P/O d-? s:- a?
