Estou tentando instalar o matplotlib para aplicações gráficas em Python no Mac OS X. Quando executo "python setup.py install", isso gera um monte de erros:http://pastebin.com/u7fL37ic.

Um snippet rápido:

Instalei o freetype usando o MacPorts e achei que isso resolveria o problema, mas sem sorte. Dá-me o mesmo erro de antes. Parece que não consegue encontrar os arquivos do tipo freet certos:

BUILDING MATPLOTLIB

                    * of '.', './freetype2'.

Onde devo colocar os arquivos do tipo livre para que possam ser encontrados? No momento, eles estão em / opt / local / lib

Alguma ideia?
