angstrom is a lite weight distribution for embedded devices 
http://www.angstrom-distribution.org <http://www.angstrom-distribution.org/>
Its what gumstix supplies as default in the factory programmed images 
and in the development environment
and their downloadable prebuilt images.

Just download an image instalk to sd, plug itin and be up and running 
within 30 minutes (or less).

All the information is here 
http://www.gumstix.net/Setup-and-Programming/cat/Overo-Setup-and-Programming/111.html
You just need to carefully read through it.


Factory images are at
http://www.gumstix.net/factory_images/

Prebuilt images at
http://www.sakoman.com/feeds/omap3/glibc/images/overo/

Trying to use desktop images/software  on embedded hardware is just 
going to cause you lots of hassles and waste yours and everyone elses time.

Depending on what you need you maybe able to add to a basic ansgstrom 
image by using opkg (package manager)
without needing to cross compile anything.

On the default image with the gumstix connected to a network , try
opkg update                (to get the latest list of packages)
opkg install python


The latest image I have installed has bash as the default shell
eg

root@overo:~# help
GNU bash, version 3.2.39(1)-release (arm-angstrom-linux-gnueabi)
These shell commands are defined internally.  Type `help' to see this list.
Type `help name' to find out more about the function `name'.
Use `info bash' to find out more about the shell in general.
