[SciPy-User] build scipy on osx lion : KeyError: 'FARCHFLAGS'

[Samuel John]

Hi,

perhaps you need the "right" gfortran compiler. I am not sure because you have /usr/bin/gfortran.

I find it most easy to get via http://mxcl.github.com/homebrew/ .
Do:
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
then do:
brew install gfortran

Then try your build again. For me this works great on Lion.
Does this help you?
