A few things,
First, try this when creating your uniform_01 object,
typedef boost::uniform_01<boost::mt19937> random_real; <--you typedef'ed it here.
random_real actual_generator;
actual_generator() <----to output numbers between 0 and 1.
Two, don't use uniform_01. The uniform_real class works much better and defaults to between 0 and 1.
Three, it looks like you are wanting random ints 0 and 1, not random real numbers between 0 and 1. For this have a look at the uniform_int or uniform_smallint class. They are probably what you are looking for.
Hope this helps.

What is the correct boost::random library resource to code this?
I've attempted to use uniform_01, by creating an instance of it with
this type:
typedef boost::uniform_01<boost::minstd_rand, double> rand_gen_t;
However, after getting it constructed as a class attribute, I find
accessing it with:
cout << (*pRand_gen++) << endl;
It produces numbers like 1 134784888 134784288 2 134784845 134784224
134785176 5 0 134784376 134785328 0.
What I want is a sequence like 0 1 0 1 0 1 0 0 0 1 1 1 1 0 1 0 1 that is
sort of random.
