用自己的overlay后，emerge -avDu world出错，如何解决？

jiyongguang

今天自己建了一个overlay,
#mkdir -p /usr/local/portage/my_overlay
然后在make.conf里添加了
PORTDIR_OVERLAY="/usr/local/portage/my_overlay",
在my_overlay里面建了dev-dotnet的文件夹，并且添加了glade-sharp和gtk-sharp，而后将bugs.gentoo上的ebuild分别下载到对应目录，执行
#ebuild glade-sharp-2.12.1.ebuild digest
#ebuild gtk-sharp-2.12.1.ebuild digest
而后emerge这两个包，成功
之后再执行emerge -avDu world的时候，出现下面的错误：

Calculating dependencies... done!
[ebuild     UD] dev-dotnet/gtk-sharp-2.10.2 [2.12.1] USE="-doc" 2,089 kB [1=>0]

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

dev-dotnet/glade-sharp:2

  ('ebuild', '/', 'dev-dotnet/glade-sharp-2.10.0', 'merge') pulled in by
    @world
    ('installed', '/', 'dev-dotnet/gconf-sharp-2.16.0', 'nomerge')

  ('installed', '/', 'dev-dotnet/glade-sharp-2.12.1', 'nomerge') pulled in by
    ('installed', '/', 'media-gfx/f-spot-0.5.0.2', 'nomerge')
    @world

dev-dotnet/gtk-sharp:2

  ('ebuild', '/', 'dev-dotnet/gtk-sharp-2.10.2', 'merge') pulled in by
    @world
    ('ebuild', '/', 'dev-dotnet/glade-sharp-2.10.0', 'merge')

  ('installed', '/', 'dev-dotnet/gtk-sharp-2.12.1', 'nomerge') pulled in by
    ('installed', '/', 'media-gfx/f-spot-0.5.0.2', 'nomerge')
    @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.

还需要适配于glade-sharp-2.12.1、gtk-sharp-2.12.1的gconf-sharp
……dev-dotnet/gconf-sharp-2.16.0的下一个版本

谢谢，下了最新的dev-dotnet/gconf-sharp-2.16.0-r1安装就可以了，但是请问上面的错误是什么意思？只安装那两个包也可以啊！
