Thank you, Phil.
Is there any way to deliver these scripts as Python scripts so I can do "python sip-install.py" versus "python_d sip-install.py"? That seems an easy solution unless I am missing something.

You implicitly choose it when you chose the version of pip to install it.
Recent versions of Python have changed the way Windows debug versions are handled. This is not yet reflected in SIP.

Use sip-build with the --no-make option and run nmake overriding make variables on the command line (I'm assuming nmake works the same was as make in this respect).
