Unless /home/{yourname}/bin is on your PATH, the make install should not cause a problem and cleaning up from it probably is fine. I'm surprised there is no /home/{yourname}/share also because make install will move man pages into it - although you might not have all of the man pages installed (that is another topic and make target - my platform does not have a port of the Asciidoctor tool, so I can't build git man pages, so I use quick-install-man, which depends on having a clone of the man page repository that the really awesome git team creates). It might be helpful to specify some of the option defines described in the Makefile so that the install goes to the proper place (like /usr/local). Run 'uname -s' to figure out which system type config.mak.uname is going to use, and go from there.

Good luck.
