 * You need to build kde-base/kdelibs with opengl use flag enabled.

[snip]

But kdelibs has no opengl in IUSE:

carcharias # emerge -pv kde-base/kdelibs

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

Perhaps you meant to require opengl for x11-libs/qt?

emerge --info

Some additional info...it looks like portage sticks whatever flags are in
effect at the time of a build into the package database, regardless of what
shows up in IUSE.  So if someone has opengl set globally or specifically for
kdelibs in package.use, then opengl will end up in vardb USE.  This appears
sufficient for the built_with_use check to pass.

Sigh, I've fixed this in krita before, now KOffice is done, too.

Thanks for reporting.
