Sure, but it seems that I just have the library misconfigured is all.

The library doesn't seem to depend on header order unless used in a way
that differs from how it is configured. Which I think is perfectly
reasonable (all bets are off if you lie to it and configure it to think
you don't have boost then turn around and use boost with it IMO).

My clever remark was referring to the boost-lite not to the header ordering.
