It happens that I require that RSS USE with kde-base/plasma-workspace, thus enabled kde-base/kdelibs[semantic-desktop], kde-base/kdepimlib[semantic-desktop] (in package.use). $ cat /etc/portage/package.use | grep semantic-desktop kde-base/kdeplasma-addons -desktopglobe -semantic-desktop kde-base/kdelibs semantic-desktop kde-base/kdepimlibs semantic-desktop #kde-base/kdeplasma-addons semantic-desktop #kde-base/plasma-workspace semantic-desktop #kde-base/activitymanager semantic-desktop #kde-base/dolphin semantic-desktop #kde-base/gwenview semantic-desktop But I don't require it for anything else.

But I need semantic-desktop in kdelibs and kdepimlibs indirectly cause - equery depends kde-base/kdepimlibs * These packages depend on kde-base/kdepimlibs: ... kde-base/plasma-workspace-4.7.4 (rss ? >=kde-base/kdepimlibs-4.7.4:4[aqua=,semantic-desktop=]) ... I need that rss USE. The cat /etc/portage/package.use | grep semantic-desktop appears to be wrong, this's what I really meant - kde-base/kdeplasma-addons -desktopglobe -semantic-desktop kde-base/kdelibs semantic-desktop kde-base/kdepimlibs semantic-desktop kde-base/kdeplasma-addons -semantic-desktop kde-base/plasma-workspace -semantic-desktop kde-base/activitymanager -semantic-desktop kde-base/dolphin -semantic-desktop kde-base/gwenview -semantic-desktop i.e. I just need kde-base/kdelibs[semantic-desktop] and kde-base/kdepimlibs [semantic-desktop] for kde-base/plasma-workspace[rss]. For rest of the packages, I don't need it. Then - emerge -pv --newuse --autounmask=n world These are the packages that would be merged, in order: Calculating dependencies ... done! emerge: there are no ebuilds built with USE flags to satisfy ">=kde-base/kdelibs-4.7.4:4[aqua=,semantic-desktop=]". !!!

Yeah, stupid mistake.

The intention of the message is to give you a choice between two possible actions. That's why it says "One of the following packages". It wants you to choose one of these package/USE combinations. > After that -- > > (dependency required by "kde-base/kdeplasma-addons-4.7.4" [ebuild]) > > Which apparently makes no sense. The unsatisfied dependency is >=kde-base/kdelibs-4.7.4:4[aqua=,semantic-desktop=], and this atom comes from kde-base/kdeplasma-addons-4.7.4. Does that make sense?

Does that make sense? Only if kde-base/kdeplasma-addons[semantic-desktop] is required when kde-base/kdelibs is build with [semantic-desktop]. But is that the case? Seems very unlikely. Let's take a hypothetical example. Suppose package X and Y have a common use -- h264. For Y to be compiled with h264 USE, X too has to be compiled with h264 USE, thus in Y's ebuild - h264? ( X[h264]) X being a library, does not depend on Y, but Y being an application and using X, depends on it and it's capabilities. As a result, if I want Y[-h264], I may or may not build X with h264, this USE does not matter if Y[-h264] is the case. In the above case X is kdelibs and Y is kdeplasma-addons, thus kdeplasma-addons[semantic-desktop] depends on kdelibs[semantic-desktop], if I want kdeplasma-addons[-semantic-desktop], it does not matter if I build kdelibs with or without semantic-desktop. But in this particular case portage is still enforcing semantic-desktop on kdeplasma-addons, but no ebuild depends on kdeplasma-addons[semantic-desktop].
(In reply to comment #8) > Does this mean kde-base/kdelibs[semantic-desktop] depends on > kde-base/kdeplasma-addons[semantic-desktop]? Yes, and also it means that kde-base/kdelibs[-semantic-desktop] depends on kde-base/kdeplasma-addons[-semantic-desktop]. A semantic-desktop= USE dependency means both. > Only if kde-base/kdeplasma-addons[semantic-desktop] is required when > kde-base/kdelibs is build with [semantic-desktop]. But is that the case? > Seems very unlikely. Whether or not it really is the the case, that's the meaning of the dependency. If the dependency is expressed incorrectly, then you can file a bug for kde-base/kdeplasma-addons to have the dependency corrected. > But in this particular case > portage is still enforcing semantic-desktop on kdeplasma-addons, but no > ebuild depends on kdeplasma-addons[semantic-desktop]. Portage is behaving as it's designed to behave for the way that the dependency i expressed. If you think it's expressed incorrectly, then you can change the sematic-desktop= USE dependency and test to see if it works. Then you can file a bug for kde-base/kdeplasma-addons to have the dependency corrected.

A semantic-desktop= USE > dependency means both. > Ok, so, kde-base/kdeplasma-addons is not necessary, and if one has installed it, it's semantic-desktop USE should be at sync with kde-base/kdelibs's. Also it's the first time I'm listening about this '=' after a USE, it's undocumented In this case, I think equery should provide some output about this. Also where is this dependency information written? Apparently it's not in the ebuild, unless some classes got inherited.
(In reply to comment #10) > Also it's the first time I'm listening about this '=' after a USE, it's > undocumented Portage documents this syntax in `man 5 ebuild` in the "Conditional USE Dependencies" part of the DEPEND documentation. There's a reference to ebuild(5) from the emerge man page where it defines "atom". > In this case, I think equery should provide some output about this. I don't see an equery option for that. It can be queried with portageq like this: portageq metadata / ebuild kde-base/kdeplasma-addons-4.7.4 DEPEND RDEPEND PDEPEND > Also > where is this dependency information written?

DEPEND, RDEPEND, and PDEPEND can be defined directly in the ebuild and also in any of the eclasses that it inherits (see the "eclass" directory).
Thanks for the info.
