Hi, sorry for my ignorance but I have filed bug #262025. It is actually about the message being unclear, at least to me. Let's say I am used to: # emerge -pv mesa [ebuild U ] media-libs/mesa-7.3-r1 [7.3] USE="motif -debug -doc -nptl -pic -xcb" VIDEO_CARDS="radeon -intel -mach64 -mga -none -r128 -s3virge -savage -sis (-sunffb) -tdfx -trident -via" 0 kB # However, the message "dev-util/subversion[-dso]" is unclear. Probably a space is missing? Few more ideas how I would re-structure the text: The following packages have to be build with the following USE flag(s): "dev-util/subversion [-dso]" (dependency required by "dev-util/git-1.6.2" [ebuild]) (dependency required by "world" [argument]) Reproducible: Always Actual Results: emerge: there are no ebuilds built with USE flags to satisfy "dev-util/subversion[-dso]". !!! One of the following packages is required to complete your request: - dev-util/subversion-1.5.5 (Change USE: -dso) (dependency required by "dev-util/git-1.6.2" [ebuild]) (dependency required by "world" [argument])

The syntax does not allow any spaces inside a dependency atom. > Few more ideas how I would re-structure the text: > > The following packages have to be build with the following USE flag(s): > "dev-util/subversion [-dso]" You've focused on the internal dependency syntax instead of the part that's supposed to be human readable. > (dependency required by "dev-util/git-1.6.2" [ebuild]) > (dependency required by "world" [argument]) > > Reproducible: Always > > Actual Results: > emerge: there are no ebuilds built with USE flags to satisfy > "dev-util/subversion[-dso]". > !!! One of the following packages is required to complete your request: > - dev-util/subversion-1.5.5 (Change USE: -dso) The above line is the "human readable" part that you're supposed to focus on. See, it's advising you to "Change USE: -dso" for subversion-1.5.5. The output is modeled directly after the "masked packages" message, which is basically the same message as this except that it shows masking reasons instead of required changes to USE.
- dev-util/subversion-1.5.5 (Change to USE: -dso) ------------------------------------^^^ so about this?
The messaging is all well and good, but why does this happen in the first place? Normally when a use dependency is required, portage just forces the use flag on/off. Why isn't that happening here?
(clarification) I had to do USE="-dso" emerge subversion in order to fix this. I shouldn't have to do this and normally portage does it for me. Why didn't it happen this time?
(In reply to comment #4) > (clarification) I had to do USE="-dso" emerge subversion in order to fix this. > I shouldn't have to do this and normally portage does it for me. Why didn't it > happen this time? The problem is that the subversion ebuild uses an IUSE default setting to enable the dso flag (it has +dso in its IUSE variable). For bug 258371, there are plans to add automatic USE adjustment. (In reply to comment #2) > - dev-util/subversion-1.5.5 (Change to USE: -dso) > ------------------------------------^^^ so about this? I think the existing message is fine. You're the first person that's reported a misunderstanding like this. Maybe we just need to explain the existing output with some examples in the documentation.

Closing as WONTFIX.
