At the moment the dtrace project has an experimental implementation of threads merged into libc and you need to enable this by adding WITH_LIBC_THREADS=1 to /etc/make.conf. Then it will build. Also, since the KSE code in the kernel doesn't handle signals properly in a many-cpu system, in order to make progress on sun4v, the KSE code has been removed. We really need to try to make it a kernel option so that we can compare the thread implementations. Making KSE a kernel option is very messy, though. Without KSE support in the dtrace kernel, libpthread cannot work. You need to use libthr. -- John Birrell
