Impossible MAJ de portage - Gentoo OVH

Bonjour,

J'essaie en vain de mettre à jour portage. J'ai tout d'abord effectué un emerge --sync, qui m'a renvoyé le message suivant à la fin :

 * An update to portage is available. It is _highly_ recommended
 * that you update portage now, before any other packages are updated.

 * To update portage, run 'emerge portage' now.

J'ai donc fait un 'emerge portage', qui m'a donné le résultat suivant :

!!! /etc/make.profile is not a symlink and will probably prevent most merges.
!!! It should point into a profile within /usr/portage/profiles/
!!! (You can safely ignore this message when syncing. It's harmless.)

!!! All ebuilds that could satisfy "sys-apps/portage" have been masked.
!!! One of the following masked packages is required to complete your request:
- sys-apps/portage-9999 (masked by: EAPI 2)
- sys-apps/portage-2.2.0_alpha59 (masked by: EAPI 2)
- sys-apps/portage-2.2.0_alpha58 (masked by: EAPI 2)
- sys-apps/portage-2.2.0_alpha51 (masked by: EAPI 2)
- sys-apps/portage-2.1.10.19 (masked by: EAPI 2)
- sys-apps/portage-2.1.10.18 (masked by: EAPI 2)
- sys-apps/portage-2.1.10.11 (masked by: EAPI 2)
- sys-apps/portage-2.1.10.3 (masked by: EAPI 2)
- sys-apps/portage-2.1.9.42 (masked by: EAPI 2)
- sys-apps/portage-2.1.6.13 (masked by: missing keyword)
- sys-apps/portage-2.1.6.7 (masked by: missing keyword)
- sys-apps/portage-2.1.4.4 (masked by: )

The current version of portage supports EAPI '1'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.

For more information, see MASKED PACKAGES section in the emerge man page or
refer to the Gentoo Handbook.

Pour information, 'emerge --info' donne ceci :
