Arch Linux 又一坑
# 2013-03-17 刚才不小心更新了一下 curl
sudo pacman -S curl
# 结果 curl 跪了，所有的 pacman 命令也是
curl: /usr/lib/libc.so.6: version `GLIBC_2.17' not found (required by curl)
curl: /usr/lib/libc.so.6: version `GLIBC_2.17' not found (required by /usr/lib/libcurl.so.4)
# 于是很悲剧地连回滚 curl 都不行，幸好找到了不通过 pacman 命令回滚软件的方式
# https://bbs.archlinux.org/viewtopic.php?pid=1148260#p1148260
zcat /var/cache/pacman/pkg/curl-7.26.0-1-<arch>.pkg.tar.xz | tar xv -C /

还是不要用 rmagick 了吧
# https://bbs.archlinux.org/viewtopic.php?id=49632
# rmagick 的 lib 文件检测机制太老，找不到新版本的 imagemagick（~> 6.8.0），
# 回退到旧版本就好了
sudo pacman -U /var/cache/pacman/pkg/imagemagick-6.7.8.9-1-i686.pkg.tar.xz
