Sadly, in a sense, but reasonable for reproducibility, SCons appears not to use /etc/paths and /etc/paths.d/* on OSX/macOS to determine the path to search when actually building. Also Detect and WhereIs seem to have different algorithms for what the path is. In the end there is a hardwired path for execution of build rules. I understand this for reproducibility across different machines but it means Macports is discriminated against and Homebrew is discriminated for. For this and other reasons, I am about to ditch MacPorts and embrace Homebrew. This will make testing SCons D stuff on OSX/macOS a lot easier.
