        Hyper Estraier supports only the EUC-JP version of MeCab-IPADIC.
        However, you have installed the #{mecab_dic_charset} version so far.

        You have to reinstall your mecab-ipadic package manually with the
        --with-charset=euc option before resuming the hyperestraier installation,
        or you have to build hyperestraier without MeCab support.

        To reinstall your mecab-ipadic and resume the hyperestraier installation:

            $ brew uninstall mecab-ipadic
            $ brew install mecab-ipadic --with-charset=euc
            $ brew install hyperestraier --enable-mecab

        To build hyperestraier without MeCab support:

            $ brew install hyperestraier
      EOS
    else
      <<-EOS.undent
