It did indeed appear to build the python library in that case (although I missed a semicolon so it built python27 instead of python36).

I corrected my error (also scrubbing the build folder again), and this time it correctly built and installed the python36 library.
Here is the link to the output for this build

So I went back to building everything (I left the --debug-building option on) and once again, it built everything but the python36 library. Here is the link to the build output for this build

OK, I scrubbed the build folder and ran again. Here is a link to the output with -d2 --debug-configuration --with-python --debug-building on the command line (in that order)

I'm replying by re-adding some addresses, just so you don't miss Steven's reply below. Can you please try that and report back what you get ?

As before, everything seems to be built and installed, except for the
python library.
As before, Boost.Build seems to find the python installation and says
it is going to build the python library, but just doesn't seem to get
around to doing it and there don't appear to be any errors that the
build system encountered.

I don't see anything obvious either. Steve, can you help with this ?

Try `--with-python --debug-building` (--debug-building
generates way too much output if you build everything)
I suspect that you'll see "<build>no in common properties"
My best guess is that the problem is in python.require-py.
Maybe run under the debugger and set a breakpoint there.

In Christ,
