For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):

一瞬途方にくれたんですが、http://d.hatena.ne.jp/ousttrue/20091108/1257702890:Title=device-mapperがudevをblockingする件 - 三次元日誌 という記事からdevice-mapperをunmergeすればいいんだとわかってすんなり対処できました

Gentoo使い始めてもう4-5年たつけど、まだBlockingには慣れないなorz
