No se puede comstackr el origen de Dropbox a pesar de que pygtk está instalado en Arch Linux

Recientemente instalé Arch Linux en mi sistema y deseo configurar el cliente de Dropbox para que pueda sincronizar algunos de mis files con la nube. Estoy tratando de comstackr el cliente desde la fuente como lo indica el ¿Cómo construyo el instalador de Dropbox para Linux? . Sin embargo, tengo un problema, me indicó que instale pygtk , y lo he hecho con pacman, sin embargo, incluso después de un reinicio en ejecución:

 cd ./nautilus-dropbox-2015.10.28; ./configure; make; make install;

Mi sistema está actualizado, ¿qué me estoy perdiendo?

Actualización de información:

Preferiría no proporcionar el logging completo ya que hay mucha información de configuration del sistema allí que preferiría no publicar en línea por las dudas, pero aquí está lo que creo que es la parte relevante del config.log solicitado:

Pero este post de error realmente no me ayuda a entender cuál es el problema y por qué no puede encontrar pygtk .
