Thanks, but before I saw this response, I already tried simply doing
count(accum), without adding the count tag, since it seemed to be part of 
the examples shown here: http://www.boost.org/doc
/libs/1_37_0/doc/html/accumulators/user_s_guide.html#
accumulators.user_s_guide.the_statistical_accumulators_library.mean

and it seems to work (compiles, at least).
