Kris,

What about the rest of the problems mentioned with Freebsd native threads 
vs Linuxthreads?

I would really like to get MySQL installed on FreeBSD-AMD64 if possible so 
I can run
benchmarks and compare it to a Linux installation...

I'm just not sure what the best way to compile it is.

How do you compile Mysql on AMD64?
