appbuilder install failing on Linux Mint 17.1 Rebecca

Hi,

I cannot get the 'npm install appbuilder -g' command to run successfully.

I've satisfied the prerequisites by 

(1) Installing node version 0.10.38 (I used nvm rather than npm)
(2) Installing runtime libraries via 'sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 libstdc++6:i386'

Error is below.

Thanks, David.
