I've never really understood the logic behind Boost.Build's matching of alternatives. I think the messages above are probably innocuous, but they could be a problem (possibly related to https://trac.lvk.cs.msu.su/boost.build/wiki/AlternativeSelection). You should ask about that on the boost.build mailing list.
I think it is a problem. It looks like python got configured twice, and the python toolset isn't filtering out the second one even though it's the same as the first. Thus, an ambiguity. In Christ, Steven Watanabe
