we have precompiled packages for Solaris 10 Sparc that you can use at

http://support.menandmice.com/download/unbound/solaris/sparc/

There are different "flavors", Package Flags:
e - compiled against LibEvent in /usr/local/libevent
f - compiled in forked mode (non-threaded)
t - compiled from trunk sources (non-stable, non-release)
v - compiled against LibEv in /usr/local/libev

These packages install into "/usr/local/unbound-<version>", you need to
symlink to "/usr/local/unbound"

With this scheme, you can have multiple versions and flavors of unbound
installed and you can switch them by changing the symlink.

There is no universal "best" option, wether threaded or forked, with our
without Libev or Libevent depends on your traffic patterns. We have seen
best results in the large provider space with the "e" (libevent,
threaded) and "ef" (libevent, forked) versions.

--sysconfdir=/var/unbound/etc --sharedstatedir=/var/unbound
--localstatedir=/var/unbound
--with-conf-file=/var/unbound/etc/unbound.conf
--with-run-dir=/var/unbound --with-chroot-dir=/var/unbound
--with-pidfile=/var/unbound/run/unbound.pid

This options all sets the directory and file-locations

--with-username=unbound

This sets the username to use by the unbound process when it gives up
superuser (root) rights.

--with-ssl=/usr/local/ssl/

This is where the configure will find the OpenSSL installation

--without-pthreads --with-solaris-threads

This will disable the Posix Threads and will enable the Solaris own threads.
