Same error results when trying to build it manually with the same options that
MacPorts uses. When building manually on Snow Leopard I usually hack around it
with a patch like this:

This gets it to build but I don't know if it's actually correct. I'd almost
kinda prefer it if there were a configure flag to disable libsanitizer
completely for other occasions when it breaks...
