Yep, that is what I was also thinking about. However, my pkgsrc ssh
server depends on libcrypto from base:

> ldd /usr/pkg/sbin/sshd
/usr/pkg/sbin/sshd:
        -lwrap.1 => /usr/lib/libwrap.so.1
        -lgcc_s.1 => /usr/lib/libgcc_s.so.1
        -lc.12 => /usr/lib/libc.so.12
        -lcrypt.1 => /usr/lib/libcrypt.so.1
        -lcrypto.8 => /usr/lib/libcrypto.so.8
        -lskey.2 => /usr/lib/libskey.so.2
        -lutil.7 => /usr/lib/libutil.so.7
        -lz.1 => /usr/lib/libz.so.1
