The version from the ppa seems to be 1.7.0.4-1ubuntu0.2 but the version
of git being in the native ubuntu quantal repository 
(I assume you're running Ubuntu?) is already 1.7.10.4-1ubuntu1 
(http://packages.ubuntu.com/quantal/git)


However to get an unoptimized version with debug symbols you could do this:

	# get the source:
	git clone git://git.kernel.org/pub/scm/git/git.git/
	cd git

	# read INSTALL, the section starting at

	# this is a guess, maybe you need more or less packages, but you'd need the -dev packages for the C-headers
	sudo apt-get install libz-dev libopenssl-dev libcurl-dev libexpat-dev 
	
	# Now disable optimizing by overwriting default compile flags:
	echo "CFLAGS=-g" > config.mak

	# compile and install	
	make 
	make install # installs to ~/bin

	# open a new shell or relogin, and see if you're using the version you just build:
	git --version
	# git version 1.8.4.rc1....
