It's not quite that bad. You need a section with 11 includes:
// inform boost.build of hidden dependencies
# include "boost/mpl/aux_/preprocessed/bcc/_all_.hpp"
# include "boost/mpl/aux_/preprocessed/bcc_pre90/_all_.hpp"
and 11 copies of the same _all_.hpp header that consists of 47 includes and
will never change.
Ugly and error prone? No more than what's already there, I'd say.
