Install steps

1. User directory is: /Users/<user>. <top> is a directory where you like to stash such things.

2. cd ~/<top>
git clone git://github.com/tp-freeforall/macports.git

3. Edit /opt/local/etc/macports/sources.conf to include a line: file:///Users/<user>/<top>/macports

4. (for MSP430) sudo port install msp430-binutils-tinyos msp430-gcc-tinyos msp430-libc-tinyos

5. (for AVR) sudo port install avr-binutils-tinyos avr-gcc-tinyos avr-libc-tinyos avrdude-tinyos

Note: nesc 1.3.3 is in the latest macports so it can be installed by doing sudo port install nesc. However, 1.3.4 is required for mspgcc 4.7 support. 1.3.4 is provided by this macport configuration.
