In your specific case, it seems that you have disabled a protocol or
cipher or whatever, in other words you have changed the default options.
I guess the "..." in your command means just that you are omitting some
So in such case you need "make depend". What is said in point (1) is
For instance, if you compile some not-latest OpenSSL with -nossl2 (this
is the current hype), compilation will fail unless you issue "make depend".
Sorry but I don't exactly understand how you are quoting the rest, so I
cannot see exactly what is that you find confusing.
