Hi All -

You can do this quite simply with fink if you have
the patience to wait for the compilations to finish.
This works on my ppc mac  with
XCode and fink installed (12/31/2006):

  fink install scipy-py24
  sudo apt-get install gettext-dev=0.10.40-25 gettext=0.10.40-25
  fink install matplotlib-py24

For more details see this page I set up:
