You have both qt3 and qt4 use flags enabled. According to the dependency rules: ... qt4? ( !qt3? ( <----------- dev-python/PyQt4[X] dbus? ( dev-python/dbus-python ) ) ) qt3? ( <----------- dev-python/PyQt dbus? ( dev-python/dbus-python ) ) ... Which means: IF qt4 AND NOT qt3, use PyQt4 IF qt3, use PyQt-3 Basically: Qt3 is the default if both qt3 and qt4 are enabled. If you want to use Qt4 on this package, you need to disable the Qt3 use flag.

In which case this is a bug which needs to be resolved. While this may be what you were trying to get at in the first place, this wasn't clear (in my opinion). In future I would recommend you explicitly state what's actually happening and, just as importantly, exactly what you expected to happen. (This information may seem obvious to you, but is not necessarily obvious to those reading a bug which simply consists of a large amount of dumped output from various commands with little explanation) I disagree that the newer generation should always win. Often, especially when they're first released, the "newer" generation isn't supported to the same degree that the "tried and tested" older generation is. What I do agree with is that the behaviour should be uniform, so either, across the whole tree, when both flags are set: - qt4 should be preferred over qt3 - qt3 should be preferred over qt4 It would probably also be useful for users (and devs too!) to have this stated somewhere - probably in the global use flag descriptions. > > > Moreover, you are requesting the user to aggressively override > the Gentoo _system_ default settings, > which is having both enabled as _system_ settings, > as already cited above (please, re-read): > ... > + + qt3 : Adds support for the Qt GUI/Application Toolkit version 3.x > + + qt4 : Adds support for the Qt GUI/Application Toolkit version 4.x > ... You seem to misunderstand what use flags are. As a general rule, use flags are for enabling (or disabling) optional features in packages. Your selected profile will set a selection of reasonable defaults. You are then expected to fine-tune these for your preferences. There's no such thing as "aggressive overriding" - they are simply choices for you to make. > > or call up ufed ... > > or > # cd /usr/portage/profiles > and run > # grep -R "qt3" * | grep make.defaults > # grep -R "qt4" * | grep make.defaults > # grep -R "qt3" * | grep "qt4" | grep make.defaults > > - do you recognize any differences at all?

The deps should be adjusted so that qt4 will be preferred over qt3 when both are enabled (and if i understand correctly, both are enabled by default in desktop profile). As Qt team we discourage the use of Qt3, as Qt4 has been stable for a while now. So where there is a choice, we strongly recommend Qt4.
net-print/hplip-3.9.4b-r1 now prefers qt4 over qt3 if both flags are enabled.
