Yes, I agree. Again, I didn't mean to criticise the tools themselves. But
even if the ultimate problems stem from incorrect use of these tools, it's
caused by those tools being moving targets.
There were fixes to the boost.python build system even after the freeze,
and they ultimately were caused by bbv2 being relatively new and not yet well
understood and tested by a broad community. In contrast, 'make' is a very well
known and understood tool, and people know its limitations and how to navigate
around them. (For avoidance of doubt: this is *not* an argument to use 'make'
instead. My point merely is that using new and experimental tools makes for
a very fragile development platform.)

Sure. As you know there have been some problems very late in the release
cycle with boost.python tests, where accidentally a wrong python interpreter
was dragged in. Only very few people (inculding a core bbv2 developer) understood
the problem well enough to be able to come up with a fix.
