Provando a fare un nuovo aggiornamento, dopo aver riemerso portage, come suggerito dopo la sincronizzazione, è andata così:

darkstar / # emerge -DNu world
Calculating dependencies... done!

  The following REQUIRED_USE flag constraints are unsatisfied:

Cosa mi sta chiedendo di fare?
Devo aggiungere le USE in rosso?

EDIT:
Ho aggiunto queste USE, che erano in rosso

Codice: Seleziona tutto

classic egl gallium llvm (multilib) nptl shared-glapi xvmc 

E poi ho riprovato.
Mi ha dato lo stesso messaggio, solo che alla fine, le tre righe "(dependency required by ...) sono cambiate così:

Codice: Seleziona tutto

(dependency required by "x11-libs/qt-gui-4.8.1-r1[egl]" [ebuild])
(dependency required by "x11-libs/qt-core-4.8.1-r3[qt3support]" [installed])
(dependency required by "app-text/poppler-0.18.4-r1[qt4]" [installed])
(dependency required by "net-print/cups-1.5.2-r4" [installed])
(dependency required by "app-text/ghostscript-gpl-9.05-r1[cups]" [installed])
(dependency required by "net-print/foomatic-filters-4.0.15" [installed])

Sono disorientato. Io le USE gliele ho date, ma lui le chiede ancora?

EDIT:
Mi correggo. Anche il primo rigo è un pelo differente. Questa volta dice:

Codice: Seleziona tutto

!!! The ebuild selected to satisfy "media-libs/mesa[egl]" has unmet requirements.

Ma per il resto è proprio uguale.

[conoscenza]

...mmm no!
Togli le use che hai aggiunto, riprova e posta il risultato.

Poi mostra:
cat /etc/make.conf
cat /etc/portage/package.keywords
cat /etc/portage/package.mask
cat /etc/portage/package.use

[Zievatron]

Ovviamente, è lo stesso della prima volta.

Ok.
Aggiungi "g3dvl" alle USE in /etc/make.conf, poi riprova.

[Zievatron]

Mi sta scaricando 77 paccheti!

[conoscenza]

Ottimo.

xvmc? ( g3dvl )

significa:
"ho xvmc quindi ho attivi anche g3dlv oppure disattivi anche xvmc"

[Zievatron]

Ma xvmc era tra i rossi! Allora i rossi sono quelli che si hanno già?

[conoscenza]

Tutte queste legende non le so.
Però so di quella rappresentazione "use1? (use2)" e controllando in make.conf avevi, effettivamente, use1!
