How do I install scipy, numpy and scikit
I have been trying to install scipy, numpy and scikit-learn on snow leopard with python 2.7 but without success so far.
All I can find is for Lion which I can't upgrade to. I successfully installed python 2.7, pip, virtualenv, virtualenvwrapper and numpy. But when I tried to install scipy I got this error.

I have gcc and g++ 4.2 installed and I think I have found out that it should be for gcc, g++ 4.0 which I don't know how to install.
What should I do to successfully intall scipy, numpy and scikit-learn on Snow Leopard?
Thanks very much.
EDIT: I use brew install python to install python 2.7.3 and I have Xcode 4.2 installed on my snow leopard. And the above is the error I got when I was trying to install scipy.
And when I look into my /usr/bin I only have g++, g++-4.2
g++ is also version 4.2.1
I only have Xcode 4.2 installed too, but managed to found a gcc-4.0 on my system that worked. Not sure how it got there, but I suppose it came with Xcode 4.2.
So, before installing an older version of Xcode you may want to check if you have a gcc-4.0 in this location:
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/
All I did was to run this:
export CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.0
export CXX=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.0
export ARCHFLAGS='-arch i386 -arch x86_64'
... before installing scipy:
pip install scipy
