No, the default option is still to use distutils (the setup.py files).
But the scons scripts are maintained and should work on most platforms
(I almost exclusively use the scons build myself).

You downloaded a development version, so things may be broken. To get
the exact error, you can look at
build/scons/scipy/lib/lapack/config.log, and paste this output.
