Answering your 1st email:
Recipes inheriting scons I found in my meta's were:

pingus mongodb mixxx gpsd

* gpsd do_compile is broken for me without this patch (not findinig
math lib although -lm is in ld's command line)
* all others I tested here

Answering your 2nd email:
All files are recompiled without actually doing something. If somebody
has the time for it - it might be useful to see what happens

* if we skip do_compile completely or
* what causes scons to force a recompile although it is told to install

To be honest: Scons is yet another build system doing same thing as
others and creating it's own bugs (e.g pkg-config variables). I
wouldn't want to spend too much time on because there are fortunately
only few packets using it.
