我正在尝试在我的 Gentoo 网络服务器上安装 git。命令“emerge dev-vcs/git”返回以下结果：
* IMPORTANT: 12 news items need reading for repository 'gentoo'.
* Use eselect news read to view new items.
* IMPORTANT: 5 config files in '/etc/portage' need updating.
* See the CONFIGURATION FILES section of the emerge
* man page to learn how to update config files.

!!! Multiple package instances within a single package slot have been pulled

=dev-lang/perl-5.16* required by (virtual/perl-libnet-1.230.0:0/0::gentoo, installed)
^ ^^^^^
dev-lang/perl:0/5.16=[-build(-)] required by (perl-core/File-Temp-0.230.400-r1:0/0::gentoo, installed)

(and 12 more with the same problems)

^ ^^^^^
(and 2 more with the same problem)
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.
接下来，我尝试“emerge dev-lang/perl”，但它返回了相同的错误。有什么建议吗？谢谢大家！
