Code:
cloc3 /usr/local/portage/x11-apps/OpenBoard # grep USE OpenBoard-1.7.1.ebuild
IUSE="qt5 qt6"
REQUIRED_USE="?? ( qt5 qt6 )"
cloc3 /usr/local/portage/x11-apps/OpenBoard # grep -rH OpenBoard /etc/portage/package.use/
/etc/portage/package.use/x11-apps:x11-apps/OpenBoard qt5
cloc3 /usr/local/portage/x11-apps/OpenBoard # emerge -pv OpenBoard

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

Calculating dependencies -

!!! Problem resolving dependencies for x11-apps/OpenBoard
... done!
Dependency resolution took 1.15 s (backtrack: 0/20).


!!! The ebuild selected to satisfy "OpenBoard" has unmet requirements.
- x11-apps/OpenBoard-1.7.1::localPortage USE="qt5 qt6" ABI_X86="(64)"

  The following REQUIRED_USE flag constraints are unsatisfied:
    at-most-one-of ( qt5 qt6 )

Secondo me questo comportamento di emerge è scorretto, perché la riga REQUIRED_USE="?? ( qt5 qt6 )" dovrebbe accettare le seguenti situazioni:

    - nessuna use presente;
    - solo qt5 presente (e non qt6);
    - solo qt6 presente (e non qt5);


se ho torto, come devo impostare REQUIRED_USE per ottenere l'effetto che desidero?

Se vuoi ottenere la seguente situazione
    - nessuna use presente;
    - solo qt5 presente (e non qt6);
    - solo qt6 presente (e non qt5);

il vincolo di REQUIRED_USE che hai inserito è corretto.
Infatti stai cercando di di compilare OpenBoard con qt5 e qt6 abilitati e questo non è possibile con il suddetto vincolo.

accipicchia.
avevo impostato le package.use senza controllare il make.conf
così è meglio:
Code:
cloc3@cloc3 ~ $ grep -rH OpenBoard /etc/portage/package.use/
/etc/portage/package.use/x11-apps:x11-apps/OpenBoard -qt5 qt6
