I wanted to do an experiment with SCons 4, and discovered that it doesn't work with --build-tools=next on master.
$VIRTUAL_ENV/bin/scons --variables-files=etc/scons/xcode_macosx.vars configure
Works on my macOS machine, but
$VIRTUAL_ENV/bin/scons --variables-files=etc/scons/xcode_macosx.vars configure --build-tools=next
does not. It fails during the configure checks:
scons: Reading SConscript files ...
scons: running with args /Users/acm/.virtualenvs/mongo/bin/python3 /Users/acm/.virtualenvs/mongo/bin/scons --variables-files=etc/scons/xcode_macosx.vars configure --build-tools=next

Looking in config.log shows that SCons has failed to substitute something, expanding it to a python stringification rather than having called the function:
