System cannot verify certificates from any HTTPS connections

As the title says, my system fails to verify security certificates for secured connections. This can be worked around, using a configuration file (for cURL), and "--no-check-connection" (for wget), but I can't always work around this issue, and until I get this fixed, I cannot install a web browser, I cannot use chat programs, installers/packages fail if they need to connect to the Internet, and I am really frustrated.

I have recompiled and reinstalled GnuTLS, cURL, OpenSSL, NSS, make-ca, but it still won't work. I use the default directories, as per BLFS, but I can't seem to get my connection to work. Does anybody know how to fix this? This problem affects the console, as well as GUI applications.

Thanks for the help!
