apparently the extra -Wl is  not necessary, since when i leave it off,  
it still gets sent, probably due to the macosx-min-version flag.

WITH:
 > ./bjam macosx-version-min=10.4 architecture=combined linkflags="-Wl  
-force_cpusubtype_ALL" --with-thread -a -n install

     "g++" -dynamiclib -Wl,-single_module -install_name

note: see it's in there TWICE?  is the problem that i'm missing a comma?
