ブログ - pdfでdiffをとるdiff-pdf
diff-pdfのパッケージを確認．
インストールされてない依存関係のあるパッケージがあるので，次々とインストールしていく．
まずはautomake．
問題なく終了．次はwxmac．これはCross-platform C++ GUI toolkit．
次に，cairo．Vector graphics library with cross-device output supportとある．
そしてX11を．
エラーがでた．x11vncをインストールしろとのこと．VNC server for real X displaysです．ライブラリ利用ようかなぁ．
問題なくx11vncはインストール完了．次に，XQuartzが入っているか確認．
インストールされてない．
macOSでX Windowを使うには，XQuartzが必要なのでインストールしておく．
xquartzのインストールが終わったので，依存関係が解消しているか確認．
x11も入っていることとして認識されている．
本体の，diff-pdfをインストール．
問題なくインストールされました．X11をインストールするのにXQuartzを入れるというのがキモかな．

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because some formulae require a newer version of libffi.
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/libffi/lib
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/libffi/lib/pkgconfig
