Thanks for following up.

- The path /sw/lib/gcc4.4/bin is indeed that which shortcut 
/sw/bin/g++-4 points to.
- The configuration is in 
/usr/local/boost-trunk/tools/build/v2/user-config.jam.
- find / tells me the only other user-config.jam's are in 
~/sandbox/somewhere and I doubt that bjam looks there.
- In particular, I have not had to ammend ~/user-config.jam as it does 
not exist.
- If you see to it differently (about its existence), let me know.

In user-config.jam I tried both

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

and

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

with similar results:

Undefined symbols:

"file was built for unsupported file format which is not the 
architecture being linked (i386)" is perhaps revealing that I shouldn't 
mix a ported compiler with toolset=darwin? So I tried

  using gcc : 4.4 : g++-4 : <linkflags>\"-L/sw/bin\" ;

$sudo bjam toolset=gcc-4.4
