Hi Simon-Bernard,
X509_check_ca became available in openssl-0.9.7f. I will alter ldns
configure such that it will disable dane altogether when X509_check_ca
is unavailable. I will supply you with a patch when I have done it.
Alternatively you could try to compile with openssl-0.9.7f or higher.
Best regards,
