Hi there. The new porter boxes are now available for use. See: https://wiki.linaro.org/WorkingGroups/ToolChain/Hardware
for details.
These are PandaBoards with 768 MB of memory, a USB HDD, and a good internet connection. They can be used for day to day jobs like building programs, triaging bugs, and running benchmarks.
Use dchroot natty to switch into the chroot. Use sudo apt-get install yyy to install packages. The build dependences for GCC, GDB, and binutils should already be installed.
