I'm trying to build v2.1.0-beta.1

Had numerous problems with Boost, had to try several different versions just to get anywhere near a successful compile, and still make some mods to the source (which is now pushing 6 years old)

With clang, it dumps core with an illegal instruction

With gcc, the final link fails

I've spent wayyy too much time on this. Can someone who has compiled it tell me their exact setup? Most interested in boost version, but other info would help. Thanks.
