This is the same issue as variant actually -- the boost::get thing.  The 
info object that is causing trouble in char.hpp contains a variant that 
it's trying to get a field from.  It's too bad that a later library 
(variant) reused a name from an earlier one (graph), but it's probably too 
late to do anything about either one.
