Installing unbound on openbsd 4.2

add a new/additional openssl (see http://azbsd.org/~marco/openbsd/pound/), without this you will probably get an “undefined reference to `EVP_sha25″… compile error
compiling unbound:

ldns: ./configure –with-ssl=/usr/local/openssl, gmake, gmake install
unbound: ./configure –with-ssl=/usr/local/openssl, gmake, gmake install
..
