おっと、依存ライブラリに不足があるのですね。 freetype, png が無いとおっしゃるのですが、これらは、python-freetype, libpngという名前でyumに居るようです。

MS Azure Information Protection を入れたら右クリックの「分類して保護する」がうざい

 社給PCで、Microsoft Azure Information Protection Viewerを入れる必要があり、とりあえず入れた。 その後、エクスプローラでどのファイルを開いても右クリックしたときのコンテキストメニューに「分類して保護する」という項目が出てきて、いつものエディタで開きたいのに間違って選んでしまうイライラが最近多くなった。 ので、消すことにした。 ちなみに、端末はWin8.1。
