and in the case with the 4-5 SConscript files, what happens if you run 
the same build again? Does SCons correctly report that all targets are 
"up-to-date"?

For debugging, you may start by using the "--debug=explain" option when 
calling SCons. It should tell you why the targets get rebuilt...I 
suspect it has something to do with your custom Builder, triggering 
always (!) a build.

Best regards,
