I didn't realize that 1.0rc2 was not a recent release. Authors usually
have at least source tarballs of releases that aren't over a year old
available. How am I to know if I what I get from a snapshot is even
remotely usable?

It supports prescott (and therefore SSE3), but not core2 (SSSE3). What I
was building, however does not support SSE3, meaning the highest
optimization that both could support was pentium-m.
