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.
