Qiita-Markdown gem
qiita-markdownというgemがあるのを知ったので、早速インストールしてみたところ、、、
gem "qiita-markdown"
bundle install --path .bundle
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Make sure that `gem install charlock_holmes -v '0.7.3'` succeeds before bundling.
エラーになりました。
*で囲われたあたりに、icu4cをインストールせよと書かれているので、やってみます。
brew install icu4c

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
OS X provides libicucore.dylib (but nothing else).
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/icu4c/lib
CPPFLAGS: -I/usr/local/opt/icu4c/include
==> Summary
? /usr/local/Cellar/icu4c/54.1: 242 files, 65M
すると、今度はこんなエラーが。。。

「CMake is required to build Rugged.」なんて書いてあるので、cmakeをインストールします.
brew install cmake

権限が無いと言われました。
--forceオプションを付けても駄目。
Cmake fails to install on 10.10 due to sphinx この辺を読みつつ、
対象のディレクトリへのアクセス権を与えます。
cd /usr/local/share/man
sudo chown -R $USER man7
brew link --force cmake

うまくいきました！
もはやここまで来ると、最初に何がしたかったのか思い出すのに一苦労です。
そうです、bundle installしたかったのです。
改めて
bundle install --path .bundle
うまくいきました！！
