Your problem is here, but I bet you can find it yourself if you read the 
docs on extracting results: http://tinyurl.com/2q2ttl 
(http://boost-sandbox.sourceforge.net/libs/accumulators/doc/html/accumulators/user_s_guide.html#accumulators.user_s_guide.the_accumulators_framework.extracting_results)

Hint: feature tags are in the "tags" namespace, but extractors are not.

And for the return type of the density extractor, you should look at the 
docs for density: http://tinyurl.com/3ycetz 
(http://boost-sandbox.sourceforge.net/libs/accumulators/doc/html/accumulators/user_s_guide/the_statistical_accumulators_library.html#accumulators.user_s_guide.the_statistical_accumulators_library.density)
