This was recently fixed to work on Fedora 17 if no scons is installed on the host by setting the PYTHONPATH to where BitBake has installed scons. However, if an older version of scons than 2.3.0 is installed, then it still breaks. This is due to how scons tries to determine its installation by searching through standard paths. If it finds an old installation it prepends that path to sys.path thereby causing it to ignore the PYTHONPATH. The solution is to instead set SCONS_LIB_PATH which works both if scons is not installed and if an older version is installed.
