I thought it was an error always occurring, but there is an extra
condition that is required to trigger it - an extra project.

So here is the minimum configuration I have provoked the message with:

Standing in a directory (3rd) with an unpacked boost_1_49_0, and a
directory named xyzzy, and the following Jamroot:
Jamroot:
use-project xyzzy : xyzzy ;
alias json : xyzzy//xyzzy ;

alias boost_system : boost_1_49_0//system ;
alias boost_thread : boost_1_49_0//thread ;
alias boost : boost_thread boost_system ;

in xyzzy:
Jamfile:
lib xyzzy : t.cpp ;
t.cpp:
void f() {}

$ export BOOST_ROOT=$(pwd)/boost_1_49_0/tools/build/v2
$ ./boost_1_49_0/bjam
provokes the long error message about missing argument for the tag
command.
