Okay. This is a rather hypothetical example, since alsa is masked on relevant profiles, but it's a nice, easy to understand case that's on a worryingly common theme. Say you create a new package, which we'll call mysoundthing. You add mysoundthing 1.1 to the tree, and it picks up a ~sparc keyword. Along comes mysoundthing 1.2, complete with optional ALSA support. You add in a dep of alsa? ( whatever the alsa libraries are these days ), and try to commit it. Repoman complains that the alsa libraries are unkeyworded on sparc. Now, you've heard that dropping keywords is bad. But you have a clever idea, and make the dep alsa? ( !sparc? ( alsa libraries ) ). This gets past repoman just fine. Along comes 2006 (or late 2005), and some sparc profiles get working ALSA support. So, the ALSA libraries are keyworded / profile masked as appropriate. Along comes joeuser, who installs mysoundthing. He wants ALSA support, so he turns on the alsa USE flag. Sure enough, emerge -pv indicates that ALSA will be enabled. However... Because of the nasty !arch? hack, he won't get alsa support until the arch team goes through and fixes this ebuild (and probably several others too...). The correct solution is to get the alsa USE flag use.masked on various profiles (as, in the alsa case, it is). However, there are a whooole load of ebuilds in the tree that don't do this properly. Scary sidenote: a similar hack has lead to some forums users suggesting that the way to avoid getting mozilla as part of gnome was to use USE="mips". This issue has been a major pain in the ass for some of the arch teams, and it will very likely be another major pain in the ass in the future, again and again. -- Ciaran McCreesh : Gentoo Developer (Wearer of the shiny hat) Mail : ciaranm at gentoo.org Web : http://dev.gentoo.org/~ciaranm
