It comes from http://pdb.finkproject.org/pdb/package.php/gcc44
I did:

  using darwin : 4.4 : /sw/lib/gcc4.4/bin/g++ : 
<linkflags>\"-L/sw/lib/gcc4.4/bin\" ;

and

  sudo bjam toolset=darwin-4.4

and apparently it works! But unfortunately, not with

  sudo bjam toolset=darwin-4.4 cxxflags=-std=c++0x

which was the reason for porting from unix in the first place:

cc1plus: error: unrecognized command line option "-std=c++0x"

     "g++"  -ftemplate-depth-128 -O0 -fno-inline -Wall -g -dynamic 
-no-cpp-precomp -gdwarf-2 -fPIC -std=c++0x -DBOOST_ALL_NO_LIB=1

"../../../../../bin.v2/libs/assign/v2/test/unit_testing/utility.test/darwin-4.4/debug/utility.o" 
"utility.cpp"

Replacing darwin by gcc in both user-config and bjam yields:

  sudo bjam toolset=gcc-4.4
