I don't think it's possible for a change in 1.69 to affect how 1.66 is built. Something else must be wrong.

I think the point was that newer GCC changed how the version was reported. 1.69 knows about that change and accommodates it, while 1.66 doesn't, and breaks. So either using newer Boost or older GCC is required.
