This short guide assumes you're on Ubuntu 11.04

First, we need to create directories for the build:

$ mkdir -p ~/bin

$ mkdir -p ~/android/system

Now we'll need repo. Let's download it and make it executable:

$ curl http://android.git.kernel.org/repo > ~/bin/repo

$ chmod a+x ~/bin/repo

Log out and back in so the changes take effect.

Now initialized the repository and pull the source (with my repos attached):

$ cd ~/android/system/

$ repo init -u git://github.com/playfulgod/android.git -b gingerbread

$ repo sync -j16

Depending on your connection, this might take awhile.

We will need to reuse some proprietary files.

$ cd

$ cd ~/android/system/device/huawei/m835/

$ ./extract-files.sh

Once thats done you can start compiling.

Follow the aosp instructions on setting up the build environment. - http://source.android.com/source/download.html

When the environment is setup, we need to grab a copy of Koush's ROM Manager. This is necessary to build CM7.

$ cd

$ ~/android/system/vendor/cyanogen/get-rommanager

Now, we build:

$ cd ~/android/system

$ . build/envsetup.sh && brunch m835

If the build was successful, you can now take the update zip found in out/target/product/ascend/ and flash using a custom recovery. Make sure to grab the latest Gapps to complete the experience.
