I think he meant _other_ libraries than libcurl. I'm sure you link with

I think you should look up the errno codes in your man pages and see what
those numbers mean, and also check why they are returned.

As you said yourself, it doesn't do this on other platforms and no one else
has reported this kind of problems.

You said it worked when you ran as root, so why does connect fail in both
cases?
