I know I'm late to this thread, but as a warning to anyone else: Boost 
is *not a simple recipe*.  Boost has a custom build system that is - to 
put it politely - quite challenging to use.  I recommend browsing the 
recipe and observing at what point the original author of the recipe 
started to go mad.
