最近OSX10.8（Mountain Lion）にアップグレードしましたが、プロットラベルでラテックスマークアップを使用しようとすると、Pythonのインストールが誤動作します。

次のコードは完全に実行されます。

plt.figure()
plt.plot( rand(51), rand(51) )
plt.show()

ただし、これは行いません。

plt.rc( 'text', usetex=True )
plt.figure()
plt.plot( rand(51), rand(51) )
plt.show()

私が返すエラーは次のとおりです。

多分TeXとユーティリティはあなたにありません$PATHか？コマンドラインで「tex」または「kpsewhich」と入力した場合にそれらのプログラムを呼び出すように設定する必要があります（つまり、「command notfound」ではなく出力を取得します）。以前にTeXLiveをインストールした場合は、それ/usr/texbinが検索パスにあることを確認してください。
