Thank you for the answer and for your time.

I read the manuals within the boost.jam comments. I tried to use it, but 
encountered a problem.

1. First issue
----------------

I put the boost configuration into project-config.jam and it looks like this

...

if $(use-pre-built-boost)
{
   ECHO "Using boost pre-built libraries" ;

   using boost
     :
       1.46
     :
       <include>$(BOOST_INCLUDE_PATH)
       <library>$(BOOST_LIBRARY_PATH)
     ;
} else
{
   ECHO "Using boost source tree" ;

   using boost : 1.46 : <root>$(BOOST_ROOT) ;
}

...

If I use a source tree everything is ok and get compiled, but if the 
pre-built library is used I get the error on first boost usage:

Unable to find file or target named
error:     '/boost/filesystem//boost_filesystem'
error: referred from project at
error:     '.'

If I specify --debug-configuration I get the notice from boost.build

notice: using boost library 1.46 <include>C:\Boost\include\boost-1_46_1 
<library>C:\Boost\lib

that means the 'using' rule is called and worked out.

Where am I wrong?

2. Second issue
----------------

How to avoid explicit specification of boost version while declaring boost?

In case of boost source tree (BOOST_ROOT) I can use something like this

use-project boost : $(BOOST_ROOT) ;

But I want to use pre-built boost with no version specified, i.e. I only 
want to specify BOOST_INCLUDE_PATH and BOOST_LIBRARY_PATH

When I try to omit the version I get the error.

using boost
     :
     :
       <include>$(BOOST_INCLUDE_PATH)
       <library>$(BOOST_LIBRARY_PATH)
     ;

How can I achieve the desired?

Thank you.
