A non-Boost form would be preferable.  :-)

Seriously, Boost would be YABuildDependency that probably won't fit very 
well into the current build process.

I would suggest using the C code from the standard library. The seed 
should be settable from a Python int or long as in the standard library, 
but it should also allow seeding from some kind of array to utilize the 
full 624*4 bytes of state. The coverage of distributions (gamma, beta, 
multivariate_normal, etc.) should be the same such that the new module 
can plug in seamlessly.
