Exagon, FWIW, I'm getting a similar error about parse_rule being 
undefined; however, mine is with the code which Peter Gerell
uploaded here:


https://github.com/pgerell/boost_1_61_problem

I'm trying to figure out why.  However, Peter indicates he
had to problem with 1.60.0 but only with 1.61.1.

The mystery deepens ;(

Anyway, my link error includes:
