The output says:

XXXXXXXXXXXXXXXXXXXXXXXXXX 4.2

So this means the version check fails because it expects a trailing
".0" from $(version) when what we get is just 4.2 -- consider that my
~/user-config.jam has the version set explicitly:

  using darwin : 4.2 : g++-4.2 ;

I guess there would be some more additional munging of the version
parameter especially when it's not auto-discovered.

Silly question though: does Boost.Build already support regular expressions?
