Gentoo Linuxにgollumを導入する
Portageでインストールしたruby-2.0なGentooLinuxにgollumをインストールします。
gollumに必要なcharlock_holmesというgemのインストールでエラーが出てしまいます。

のLDFLAGSを編集したら通りました。
CONFIG["LDFLAGS"] = "-L. -Wl,-O1 -Wl,--as-needed -rdynamic -Wl,-export-dynamic -Wl,--no-undefined"
という行を、
CONFIG["LDFLAGS"] = "-L. -Wl,-O1 -Wl,--as-needed -rdynamic -Wl,-export-dynamic"
にすればインストールできました。
