Hmm, did you get latest on those submodules and git checkout master in each to make sure you're up to date? Assuming you have steal in the right place it should be including Envjs.
I actually made the build script create a jar automatically recently, so steps 6-7 aren't necessary anymore. I'll update the build steps accordingly soon. You just need to have jdk installed and in your path because it uses the "jar" executable.
