I recently bought a new Macbook Air, with OS X 10.6. I started using a new
package manager called homebrew (http://mxcl.github.com/homebrew/) which is
simple, clean, and git-based. I find it incredibly easy to use, and my
numpy/scipy/mpl stack (using repo MPL) installed very smoothly.
The package will build everything from scratch, and it builds python2.7 for
you.
Here is what I did on my new computer. (NOTE: I had some trouble
replicating this on an older computer, but eventually got it working. If
this doesn't work for you, let me know, and I'll give you info on the other
install I did with homebrew.)
brew install python
brew install pip
# install gfortran from here:
# http://r.research.att.com/tools/
brew install fftw
brew install suite-sparse
# based on:
http://mail.scipy.org/pipermail/numpy-discussion/2010-August/052227.html
# download numpy 1.5.1
# download scipy 0.8.0
# tarballs
# set the following environment vars:
export MACOSX_DEPLOYMENT_TARGET=10.6
export CFLAGS="-arch i386 -arch x86_64"
export FFLAGS="-m32 -m64"
export LDFLAGS="-Wall -undefined dynamic_lookup -bundle -arch i386 -arch
x86_64 -framework Accelerate"
# in numpy directory:
python setup.py build --fcompiler=gnu95
python setup.py install
# in scipy directory:
python setup.py build --fcompiler=gnu95
sudo python setup.py install
# fresh shell
pip install ipython
