Creazione di numpy per Lion Python 2.6 con supporto gfortran

Question

Sto tentando di installare numpy e scipy su Python 2.6 preinstallato fornito con Lion OS.

Ecco i passaggi esatti che sto prendendo:

• installare una nuova copia di
  • Leone,
  • aggiornamenti,
  • Xcode (da App Store),
  • Homebrew,
  • gfortran,
  • pip,
  • e numpy.
• Il passaggio successivo sta tentando di aggiornare numpy.
  Ecco cosa accade:.. (Non ho potuto postare il log completo perché io sono un utente limitato
