So we already have compatibility code to allow us to build with older versions of nettle that I've tested right back to nettle 2.4. The "cast5_set_key" method is present in the nettle 3.2 version that Programmingkid has installed. The nettle headers mangle the name 'cast5_set_key' into 'nettle_cast5_set_key', but I'm not sure where the extra leading '_' is coming from in either _nettle_cast5_set_key or _qcrypto_cipher_new. Presumably that is something specific to Os-X linking. So I don't think this is a question of incompatible older versions of nettle. Rather than is some problem with linking going on here. I'd like to see the output of 'configure' as well as the config.log and config-host.mak files that it generates when showing this error. Also I'd like the output of 'make V=1' so we see the full linker command line, not just the summary.
