I'm using the following commands from the manual to install GIT

$ tar -zxf git-1.7.2.2.tar.gz
$ cd git-1.7.2.2
$ make prefix=/usr/local all
$ sudo make prefix=/usr/local install

but I'm receiving the following exceptions

Is this because I didn't install the dependencies?

apt-get install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev

How do I install them offline?
