building docker 0.7.2 from sources on Ubuntu 12.04

I am trying to build docker from sources. I downloaded the latest release from the github.com account here:

https://github.com/dotcloud/docker/archive/v0.7.2.tar.gz

Changed one line of code to make Ctrl-p Ctrl-q into Ctrl-^ Ctrl-q:

diff utils/utils.go utils/utils.go~
483,484c483,484
<           // char 16 is C-p -- avilella char 30 is C-^
<           if nr == 1 && buf[0] == 30 {
---
>           // char 16 is C-p
>           if nr == 1 && buf[0] == 16 {

And compiled using sudo make:

It seems to be installing a gazillion different ubuntu packages, which I don't mind, only it's taking a while to download and configure them.

At the very end, I get this error:

docker run -rm -i -t -privileged -e TESTFLAGS -v /home/avilella/src/docker-0.7.2/bundles:/go/src/github.com/dotcloud/docker/bundles docker hack/make.sh binary


error: .git directory missing and DOCKER_GITCOMMIT not specified
  Please either build with the .git directory accessible, or specify the
  exact (--short) commit hash you are building using DOCKER_GITCOMMIT for
  future accountability in diagnosing build issues.  Thanks!
make: *** [binary] Error 1

Is this the right way to install this modified version of docker? The one I installed from apt-get was 0.7.1 but I wanted to modify that line of code in my copy.

EDITED:

I followed the instructions from devenvironment and got this error at the end of running sudo make build.

I re-did sudo make build after that, and then it worked. Then I followed with sudo make binary and the next step, and it worked well.
