And here is a patch for pkgsrc that updates sysutils/estd to r4.1 and
adds DragonFly support.


To enable this, you need to apply the above kernel patch, add
options         CPU_ENABLE_EST 
to your kernel config file and recompile your kernel.
Then apply the pkgsrc patch and compile/install sysutils/estd.
copy /usr/pkg/share/examples/rc.d/estd to /etc/rc.d
make it executable and add 
to your /etc/rc.conf file.
