[Boost-build] Boost Python : Using Python interpreter without installing it

Hi,

I would like to use my own compiled python.exe but there is something i
don't understand, i did like in the doc :

using python	: 2.5 : c:/temp/python_d.exe
                                : $(kenginPath)/libs/Python/include $(kenginPath)/libs/Python/PC
                                : $(kenginPath)/libs/Python/lib/windows
                                : <target-os>windows <toolset>msvc <python-debugging>on <variant>debug ;

When i build an extension with the --debug-configuration argument i can see
that :

notice: [python-cfg] Configuring python...

notice: [python-cfg]   user-specified cmd-or-prefix: "c:/temp/python_d.exe"

Marie\Home\source\trunk/libs/Python/lib/windows"
notice: [python-cfg]   DLL search path: "<empty>"

where i can see that everything is correctly set for boost python but here
it is, the capture-output rule ( for the python extension test ) runs that :

capture-output
build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext

    set Path=C:\Documents and Settings\William
Marie\Home\source\trunk\libs\Python\lib\windows;C:\Documents and
Settings\William
Marie\Home\source\trunk\libs\boost\bin.v2\libs\python\build\msvc-8.0\debug\python-debugging-on\threading-multi;C:\Documents
and Settings\William
Marie\Home\source\trunk\test\__testscript__\build\msvc-8.0\debug\python-debugging-on\threading-multi;%Path%

    set PYTHONPATH=build\msvc-8.0\debug\python-debugging-on\threading-multi
 c:/temp/python_d.exe python "src\extensions\test_sea.py"   >
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext.output"
2>&1
    set status=%ERRORLEVEL%
    echo. >>
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext.output"
    echo EXIT STATUS: %status% >>
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext.output"
    if %status% EQU 0 (
        copy
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext.output"
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext"
    )
    set verbose=0
    if %status% NEQ 0 (
        set verbose=1
    )
    if %verbose% EQU 1 (
        echo ====== BEGIN OUTPUT ======
        type
"build\testsea_ext.test\msvc-8.0\debug\python-debugging-on\threading-multi\testsea_ext.output"
        echo ====== END OUTPUT ======
    )
    exit %status%

which obviously is not going to work because of : c:/temp/python_d.exe
python "src\extensions\test_sea.py

so the error message is : 

c:/temp/python_d.exe: can't open file 'python': [Errno 2] No such file or
directory

which is normal because "python" is not a python file.

So finally my question is : why this "python" is inserted in the command, i
tried to have a look in the python.jam but i didn't find out. 

Thanks :)
