The git commands you're seeing there are probably Apple's thin wrappers that are mostly meant to provide instructions on installing XCode, but SIP is stopping you from modifying the /usr directory (ah, Apple's Infinite Wisdom).  There are discussions about working around SIP in the Apple forums [2] and Homebrew has some hints as well [3].

Thanks.  That helped.  I will summarize here what seemed to work for me 
(skipping the wailing, gnashing of teeth, Apple tech support, etc.):


[step 1] download and install "git-2.5.3-intel-universal-mavericks.dmg" 
as normal, ending with "Install successful".  Confirm that git is still 
not properly installed. Shut down or restart.


[step 2]  Boot into the Recovery partition by holding down <cmd>+R while 
power on and boot.


[step 3] Utilities > Terminal


[step 4] $ scrutil disable


[step 5] Restart normally > Terminal > sudo mv /usr/git /usr/bin/git-system


[step 6] Shut down and reboot into the Recovery partition as above.


[step 7] Utilities > Terminal


[step 8] $ scrutil enable


[step 9] Restart normally ...


*** Git now seems to be installed.  I'm still having trouble getting it 
to work properly with a private GitHub repository.  However, RStudio 
recognizes git, and I've confirmed that /usr/bin includes a subdirectory 
git-system and NOT simply git.  My problems now seem to be GitHub and 
RStudio issues.  Thanks again for your help.  I hope this summary might 
help others.  Spencer Graves
