You get get it from http://zigzag.cs.msu.su:7813/libraries.zip
but it seems you have the problem solved already.

Yes, that's what I meant.

Both are fine. If you find specifying full path to Jamfile troublesome, 
specify only $(BOOST_ROOT). I prefer full path, but don't have any reason for 
this.

There is some cost. The second method has to load all Jamfiles for boost and 
create class instances that represent main targets. I believe that the time 
for this should be fairly small, since those classes only record sources/
requirements and don't do anything.
