@theopolis what I meant to say is I would love to know or have some definition of a base environment where builds should succeed without the bottles. It is great to have a shortcut that the bottles provide, but it seems that this does not fully describe what goes into building the software from scratch. So what I am going for is not supporting all possible environments dep. builds could be thrown at - just a description of an environment where they are successful. Then I could work on duplicating it.
