Eu tive o mesmo problema. E usei um script contiki para fazer uma instalação limpa do mspgcc no ubuntu 1204LTS. Mas primeiro, instalei esses pacotes
sudo apt-get install ncurses-dev flex libgmp3-dev libmpfr-dev bison libmpc-dev texinfo zlib1g-dev automake build-essential patch
Em seguida, executei um script modificado de contiki (listado abaixo). Não esqueça de adicionar / usr / local / bin ao PATH
INSTALL_PREFIX="/usr/local/msp430"
echo The installatoin prefix:$INSTALL_PREFIX
# Switch to the tmp directory
mkdir tmp
cd tmp
