Beginning in 2020, we have stopped providing the 10.6+ installer variant for macOS since all evidence that we have is that it was used very little and there are a grower number of problems with trying to use it on very old systems, as evidenced in this issue.  Since there has been no feedback yet about not providing the 10.6+ installer variant, I am closing this issue as not to be fixed. (We continue to provide the 10.9 64-bit-only installer variant.)  By the way, this does not mean we are intentionally removing or breaking support for building and running on 10.6 systems.  It's just that we are no longer providing pre-built binaries for them.
