Проблема при установке mysql

Здравствуйте. В gentoo я совсем недавно, так что не ругайте за такие вот вопросы. Пытаюсь поставить mysql

sudo emerge mysql

Вываливается вот такое вот:

Calculating dependencies... done!
[ebuild  N     ] dev-db/mysql-5.1.67  USE="berkdb community perl ssl -big-tables -cluster -debug -embedded -extraengine -latin1 -max-idx-128 -minimal -pbxt -profiling (-selinux) -static {-test} -xtradb" 
[ebuild   R    ] virtual/mysql-5.1  USE="-embedded*" 

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

virtual/mysql:0

  (virtual/mysql-5.1::gentoo, ebuild scheduled for merge) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (virtual/mysql-5.1::gentoo, installed) pulled in by
    >=virtual/mysql-5.1[embedded?] required by (media-sound/amarok-2.6.0::gentoo, installed)


!!! Enabling --newuse and --update might solve this conflict.
!!! If not, it might help emerge to give a more specific suggestion.


!!! The following installed packages are masked:
