不能 emerge --deep --update --newuse world，怎么解决？

livecd profiles # emerge --deep --update --newuse world
Calculating dependencies... done!
[ebuild UD] www-client/mozilla-firefox-2.0.0.19 [3.0.5] USE="-debug% -filepi cker% -moznopango% -xforms% -xinerama% -xprint%"

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

www-client/mozilla-firefox:0

('ebuild', '/', 'www-client/mozilla-firefox-2.0.0.19', 'merge') pulled in by
=www-client/mozilla-firefox-2* required by ('installed', '/', 'www-client/ep iphany-2.22.3-r1', 'nomerge')
=www-client/mozilla-firefox-2* required by ('installed', '/', 'gnome-extra/y elp-2.22.1-r2', 'nomerge')
(and 1 more)

('installed', '/', 'www-client/mozilla-firefox-3.0.5', 'nomerge') pulled in by
www-client/mozilla-firefox required by world


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.

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


谢谢。

make.conf中的USE增加-firefox xulrunner，好像暂时可以继续了。

直接mask掉firefox2，嘿嘿

问题是Gnome的epiphany好像依赖Firefox 2。

mask掉是用 echo "www-client/mozilla-firefox-2.*" >> /etc/portage/package.mask ?
