咄咄怪事，emerge的问题

etheldreda

emerge --sync更新过后，emerge -uDa world更新软件，
给出以下信息：
These are the packages that would be merged, in order:

Calculating world dependencies... done!
[ebuild     UD] app-emulation/vmware-modules-1.0.0.13 [1.0.0.15]

Would you like to merge these packages? [Yes/No]
但之前明明刚刚从1.0.0.13升到1.0.0.15，觉得不对劲，就重新emerge -va vmware-modules，结果显示如下：
These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] app-emulation/vmware-modules-1.0.0.15 [1.0.0.13] 0 kB

Total size of downloads: 0 kB

Would you like to merge these packages? [Yes/No]


这到底是怎么回事呢？？？？

看UD应该知道大致的原因，man emerge里对UD的软件的介绍：

[ebuild UD] media-libs/libgd-1.8.4 [2.0.11]
              Libgd  2.0.11  is already emerged, but if you run the command, then portage  will Downgrade to version 1.8.4 for you.
              This may occur if a newer version of a package has been masked  because  it  is  broken  or  it creates a security risk on your system and a fix has not   been released yet.
              Another reason this may occur is if a package  you  are  trying  to  emerge  requires an older version of a package in order to emerge successfully.  In  this case, libgd 2.x is incompatible with libgd 1.x.  This means that pack-          ages  that  were  created with libgd 1.x will not compile with 2.x and must              downgrade libgd first before they can emerge.

看样子是第一个原因，1.0.0.15因为某种原因又被mask了，从原来的stable移动到testing了。下面是我查询的两条信息，或许可以说明问题（我是stable）：

yagami ~ # emerge --search vmware-modules

These are the packages that would be merged, in order:

好像弄明白原因了，刚才运行emerge --depclean提示
~app-emulation/vmware-modules-1.0.0.13 required by app-emulation/vmware-workstation-5.5.1.19175-r7
