It seems from the documentation that 
my $h = gsl_histogram_alloc 3;
gsl_histogram_set_ranges $h, [0, 41, 61, 100], 4;
gsl_histogram_increment $h, $_ for @values;

will do what you like, whereupon the histogram can be printed using gsl_histogram_fprintf or gsl_histogram_fscanf. (I don't understand why gsl_histogram_set_ranges needs that final argument, since it can be figured automatically once $h is known; but the documentation says it does, and I am not in a position to test.)

(Boy, gotta love those flat namespaces. I'll bet it's fun to call these functions as Math::GSL::Histogram::gsl_histogram_xxx.)
