till certain point. that's why we have an installation script for 
production and "make install" for a developer
- alternatively, if(!) its easy and smooth we can run the engine-setup 
with an answer file  or just a "dev" flag than we can call it from the 
-Psetup profile and
make a unified process

+1 and this is where the dev setup should end.

again agree but only if its simple (minimum steps, don't have to follow 
a long and detailed wiki) and fast.
