And the answer is... I'm just out of ideas as to what might be wrong on 
your end. I just tried what I understand to be the same sequence of 
steps you did and it works fine. Here's my run:

You can configure the location of your python installation by setting:
PYTHON_ROOT    - currently "c:/tools/python"
PYTHON_VERSION - The 2-part python Major.Minor version number (e.g.
                  "2.2", NOT "2.2.1")  - currently "2.2"

The following are automatically configured from PYTHON_ROOT if not
otherwise set:

     PYTHON_LIB_PATH       - path to Python library object; currently

I even tried running it without c:\MinGW\bin in the PATH and I do get an 
error. But not the spawn error:

**OK**
On further investigation I found one difference that is pertinent from 
my runs. When I run bjam with mingw it runs command with temporary batch 
files. Which one can see with the -d+4 option as "Executing through .bat 
file" debug messages.

If I run bjam with -sJAMSHELL=%, which is what makes it run commands 
directly I get:

C:\Boost\boost_1_31_0>c:\cvsroots\boost\bjam_src\bin.ntx86\bjam 
-sTOOLS=mingw -sMINGW_ROOT_DIRECTORY=c:\MinGW -d+4 -sJAMSHELL=%
install
Executing raw command directly
Executing command [copy] 
["bin\boost\libs\date_time\build\boost_date_time.dll\mingw\debug\boost_date_time-mgw-d-1_31.lib"] 
["C:\
Boost\lib\boost_date_time-mgw-d-1_31.lib"]
spawn: No such file or directory

Which is only a slightly nicer error than yours, but equivalent. So the 
big question is now; Do you have JAMSHELL set to "%" ??
