Emerge를 사용하여 패키지를 설치할 때 발생하는 문제

저는 젠투 포티지에 대한 경험이 많지 않아서 # emerge --ask monit nginx nodejs 젠투에 Nodejs를 설치하려고 하면 다음과 같은 오류 메시지가 나타납니다:

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

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.

그 후 시도해 보았 emerge --sync으나 emerge -u world잘 되지 않았습니다. 일부 스레드에서는 삭제해야 한다고 말하지만 ssl, 그것이 실제로 문제를 해결하는 방법인지는 확실하지 않습니다.
