hyperestraier 1.4.13

Hyper Estraier is a full-text search engine. It can be built with
MeCab support to extract Japanese keywords. Its dependencies, such
as qdbm, mecab, and mecab-ipadic, are already available as formulas
and make its installation painless.

+        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
