Hm, actually, curl-config is not wrong (by my definition). I can't be wrong,
it just shows what the contents of the variables in configure are/were at the
time it ran. If the curl-config data ends up wrong, it is because the
configure script is wrong.

The problem is thus that the configure script sets up paths for SSL to
directories that aren't correct or needed. Right?

But then, if you use --with-ssl for configure, it _will_ add those
directories. If you have your defaults in your environment already setup
correctly, then you shouldn't even need the --with-ssl option (since curl's
configure script will always check for the presense of ssl in the default

I disagree. Even if some path info is wrong in the curl-config, that is the
exact information that was used to build curl. How can that be wrong if curl
built fine with it?

There's no option to curl-config to tell where the SSL libs are located, as
the configure script never really figures that out (in all cases). It
features --libs that can be used to compile and build libcurl based

I don't think I've fully understood how you're doing things. You mean you
need parts of the stuff configure sets up on --with-ssl but not everything?

Please tell me where I'm wrong and what I've failed to grasp!
