Git was installed and ready to rock, but in my first
git clone https:// (SSH ports are blocked) I received: fatal: Unable to find remote helper for 'https'.
Turns out that I was missing libcurl-devel, though I did have curl. After installing libcurl-devel and installing from sources again all worked fine.
