Ошибка при обновлении, как понять

Добрый день! Прошу Вашей помощи в следующем вопросе. Решил обновить систему:

eselect profile set 12
eix-sync
emerge -uDN (и в самом конце выдает такое) 

Calculating dependencies... done!
[ebuild     U  ] app-portage/portage-utils-0.53 [0.41] USE="nls%*" 
[ebuild     U  ] dev-libs/gmp-5.1.3-r1 [5.1.2]
…....
куча вот такого разного
…....[
[ebuild     U  ] sys-apps/calculate-install-3.1.9-r12 [3.1.9-r9]
[ebuild     U  ] sys-apps/calculate-utilities-3.1.9-r29 [3.1.9-r26]

The following mask changes are necessary to proceed:
 (see "package.unmask" in the portage(5) man page for more details)
 # required by dev-python/pyudev-0.16.1
 # required by kde-misc/synaptiks-0.8.1-r2
 # required by @selected
 # required by @world (argument)
 # /var/lib/layman/calculate/profiles/calculate/package.mask:
=dev-lang/python-3.3.3
 # required by app-portage/gentoolkit-0.3.0.8-r2[python_targets_python3_2]
 # required by @selected
 # required by @world (argument)
 # /var/lib/layman/calculate/profiles/calculate/package.mask:
=dev-lang/python-3.2.5-r3

NOTE: The --autounmask-keep-masks option will prevent emerge
      from creating package.unmask or ** keyword changes.

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

!!! The following installed packages are masked:
- dev-lang/python-3.4.0_rc3::gentoo (masked by: package.mask)
For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.

Прошу помощи для разбора и понимания следующего текста, не совсем понимаю что от меня просят. Большое спасибо за помощь!

Покажите, пожалуйста, полный вывод.
<<emerge -uDNp | wgetpaste>>

Вот что выдало:
emerge -uDNp | wgetpaste

world добавьте, забыл

Вот что выдало:

emerge -uDNp world | wgetpaste

Pasting > 25 kB often tend to fail with calculate. Use --verbose or --debug to see the
error output from wget if it fails. Alternatively use another pastebin service.
