    Probably as you built python from source, you don’t have bz2 headers.

    Install them on Ubuntu/Debian:

    sudo apt-get install libbz2-dev

    Fedora:

    sudo yum install bzip2-devel

    And build python again.
    You may notice that python checks for lots of libraries when configuring/building, if you miss some of them you probably will get no support for libs like bz2 on your case.

    You should get prebuild binaries to avoid this kind of stuff. Ubuntu 12.04 packs python 2.7.3, the version your script needs.
