I investigated the issue of using boost functions a while ago. If I recal it 
correctly the conclusion was that using the boost distribution functions would 
make QuantLib depend on some boost lib files, which wasn't regarded as 
desirable. Furthermore someone (I don't remember who) tested the QuantLib 
functions to be more efficient (less time-consuming) than the boost ones

The conclusion was to keep using current QL implementation and leave it to 
users to do the changes if they desired to use the boost ones instead
