Well I was trying to install pip (Python Package management, like CPAN for perl) and the wget did not work properly because the SSL was not from a known issuer… but here is a work around for when you have trouble…
$ wget https://bootstrap.pypa.io/get-pip.py
--2014-07-15 12:42:37-- https://bootstrap.pypa.io/get-pip.py

Just add the –no-check-certificate option into the wget, and voilá!
$ wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
