Thanks Peter! I've successfully compiled msp430-elf-gcc 4.9 using those instructions on a 64-bit Linux host.
For anyone else new to this GCC build, here's the additional steps I used to get the headers & linker scripts into the correct place: Download the GCC_RH_20131206.zip file from http://www.ti.com/tool/msp430-gcc-opensource (click "Get Software") Modify this shell script (tested under Linux only so far) to install the headers and linker scripts (change paths to install and zipfile): https://gist.github.com/spirilis/115655b9bf206402ff50 This combines memory.ld and peripherals.ld into lib/<part#>.ld as Peter suggested was needed in his quoted message. It also cleans up the ldscript directories from the include/ dir. I have successfully compiled a binary with it. ... but haven't tried it on actual hardware yet :-) Getting to that soon.
