Code:

 # emerge -upDN world

These are the packages that would be merged, in order:

Calculating dependencies /

!!! Problem resolving dependencies for x11-drivers/nvidia-drivers from @selected
... done!

!!! The ebuild selected to satisfy "x11-drivers/nvidia-drivers" has unmet requirements.
- x11-drivers/nvidia-drivers-346.35::gentoo USE="X acpi multilib tools -gtk2 -gtk3 -pax_kernel -uvm" ABI_X86="64"

  The following REQUIRED_USE flag constraints are unsatisfied:
    tools? ( any-of ( gtk2 gtk3 ) )

  The above constraints are a subset of the following complete expression:
    tools? ( X any-of ( gtk2 gtk3 ) )

(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
 #

Needless to say, X, gtk2 and gtk3 are installed, and no customization of nvidia-drivers exists under /etc/portage. It should build out of the box, no? Current running and working driver is 343.36, and I can't really make sense of the diffs between those two ebuilds.

have you set the USE flags (in make.conf or package.use) . Having a library installed doesn't mean it autosets a USE flag

Why should I have to? They're not listed in /usr/portage/profiles/use.desc.

I'll add them to the port to jump this particular hurdle ...

Princess Nell,

USE=tools gets you nvidia-settings which needs a gtk variant for its GUI.
Either drop tools or allow tools its GUI.

You have both gtk2 and gtk3 installed, and instead of telling nvidia-drivers which of them to use for its tools you disable the tools? I don't get it... nvidia-settings is rather useful, so why drop it?

I have questioned that from the moment there was a "why should I" response... Gentoo is about choice and thus you have to tell it exactly what you want ESPECIALLY as hte new nvidia-settings permits gtk2 OR gtk3

The drivers have always installed fine without any additional settings. This is changed now, and my *choice* is to disable what I don't use.

Well, this is of course your choice to make.

I just thought you like the performance and power consumption settings per application that nvidia-settings provides. Like the Powermizer. Can that be configured without nvidia-settings?

However, the default settings should just be fine... Never mind...

it can. nvidia-settings runs in 2 modes.
commandline or GUI. As nvidia shipped gtk2 and gtk3 libs gentoo took the obvious decision and gave the user the ability to control which one they want.
usually people have gtk2 in their global use flag list so it is moot.

Those that don't or heavily use per-application USE now have the option to choose what they want: gtk2 or gtk3
I really don't see how this is so controversial, VLC will not install with a gui unless you set the qt USE flag. this is a similar thing.

Nothing is controversial. It was just me getting confused about Nell complaining that both gtk versions were installed but nvidia-drivers wouldn't take both USE flags, and then removing the tools completely. That's it, really.
