[Scons-users] Builder Chains Not Working?

[Mark Ribau]

I should also note that if we have this block instead:

ret = env.MultiBuilder1("target2.json", ['target1.json', 'source2.json'])
#ret = env.Builder2("target2.binary", "target2.json")
#ret = env.InstallAs(os.path.join(installBase,"target2.binary"),
"target2.binaryplatform")
env.Alias( "myalias", True,  ret)

We end up with a target2.json file correctly.  The two commented out lines
are what cause issues.
