This is how I got Armory (etotheipi/BitcoinArmory; http://bitcoinarmory.com/) cross-compiled for the Raspberry Pi.
This is a great way to keep an air-gapped offline wallet for only $30 dollars for the RPi (that you can also use for other things; experiment, it's awesome) and $7 for a Class 10 4GB SD card, really easy to keep in a safe and secret place.
On my Ubuntu box, I had to apt-get install these packages. Your mileage may vary.

Chris Boot has an awesome post on how to setup a cross-compiler for the RPi, follow it:
http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/
But note that during the menuconfig you have to go into C-compiler → Additional supported languages and enable C++.
If you want, you can skip steps 2 to 14 (the whole menuconfig) of the second block by placing the .config file attached to this gist into the folder where you run ct-ng.
Now that you have your arm-unknown-linux-gnueabi-g++ working in your $PATH, clone the Armory repo
git clone git://github.com/etotheipi/BitcoinArmory.git
cd BitcoinArmory
Apply the attached patch to the two Makefiles (a smarter patch might be merged in the repo in the future)
patch -p1 < CXX.patch
And MAKE
CXX=arm-unknown-linux-gnueabi-g++ make
Finally, create a tarball to move to your shiny Raspberry
mkdir -p BitcoinArmoryRPi/img/
cp *.py *.so README LICENSE BitcoinArmoryRPi/
cp img/* BitcoinArmoryRPi/img/
tar cvfz BitcoinArmoryRPi.tar.gz BitcoinArmoryRPi
That's all folks!

Thanks for the great tutorial. Is there any specific version of Armory you did this for? With the latest one of the git repo (2013-01-15), I got stuck at the following. Any ideas? Cheers,
