Subject: [Boost-build] security: install rule links target in destination?

learning Boost.Build, I have the following simple Jamroot:

project maildirs
    : default-build release

install install
    : maildirs
    : <location>/usr/local/bin

exe maildirs
    : maildirs.cpp bfs
    : <include>/usr/local/include

lib bfs
    : <name>boost_filesystem
    : <search>/usr/local/lib

Running "bjam install" with insufficient privileges revealed interesting
behavior: it appears bjam runs ld on /usr/local/bin/maildirs: /usr/local/bin/maildirs
/usr/bin/ld: cannot open output file /usr/local/bin/maildirs: Permission denied

    "g++" -L"/usr/local/lib" -Wl,-rpath-link -Wl,"/usr/local/lib" -o "/usr/local/bin/maildirs" -Wl,--start-group "bin/gcc-4.2.1/release/maildirs.o" -Wl,-Bstatic -Wl,-Bdynamic -lboost_filesystem -Wl,--end-group -Wl,--strip-all

...failed /usr/local/bin/maildirs...

Security-wise, this is really undesirable. The install stage must not
do more than copy files. Am I doing something wrong in the Jamroot, or
is this "normal"? Either way, how can I achieve the desired behavior?
