That's why distros have a fairly inclusive configuration and they stick to it. No-one can cope with the combinatoric explosion of openssl configuration possibilities (even though they have ifdefs for most of them) so the only way is really to fix a standard configuration and assume you're building for it. Openssl has been talking for ages about removing engine support, but they've been unable to do so due to the rather slow pace of conversion of their own engines. I anticipate this code can be removed in favour of the pkcs11 provider long before openssl actually manages to remove engines. James
