Judging from the logs it seems that it fails at git clone on 10.8, and
segfaults on 10.6 and 10.7, which probably means that the bootstrap
binary has only been compiled for 10.8 and newer. Fixing the
certificate issue might be doable in an easier way than getting the
compiler to work on 10.6.

What might work (but I don't really know) is to download 10.6 SDK on a
new OS, install some version of stack there, and then force the
selection of C compiler, SDK, and target to compile a binary for 10.6.

It seems to me that one needs to start with a working compiler to
build a (newer) compiler, similar as you need a working C/C++ compiler
to build gcc or clang from source, except that they don't ship a
version compatible with older systems. I doubt that there is any
serious technical issue, but more of a lack of upstream interest.
