I get an error related to MkDir1-quick-fix-for-windows when building boost python.

The command I am using in the dos prompt is:
.\bjam.exe --with-python --debug-configuration --layout=system link=shared threading=multi variant=debug variant=release
The current working directory is the boost root directory.
The resulting error is:
...patience...
...found 1140 targets...
...updating 64 targets...
MkDir1-quick-fix-for-windows bin.v2\libs\python\build\msvc-8.0\debug
'C:\Documents' is not recognized as an internal or external command,
operable program or batch file.

    if not exist "bin.v2\libs\python\build\msvc-8.0\debug\\" mkdir "bin.v2\libs\python\build\msvc-8.0\debug"

And a further number of ...skipped lines one for each object file Boost.Python is composed of.
I am having difficulty diagnosing this problem as I do not know what "MkDir1-quick-fix-for-windows" is or where it is being called from in the build process.
Any help would be much appreciated.
