Can't get MUP to work on Ubuntu - path problem?

cd /usr/local/lib/node_modules/mup/node_modules

Looks like node_modules directory is here. But when type mup nothing happens? Any ideas?

ubuntu@patrick2:/usr/local/lib/node_modules/mup$ which node
/usr/sbin/node
ubuntu@patrick2:/usr/local/lib/node_modules/mup$ node -v
ubuntu@patrick2:/usr/local/lib/node_modules/mup$

sudo find / -type f -name ‘node’
/home/ubuntu/.meteor/packages/meteor-tool/.1.1.3.2hjqwt++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/bin/node -v
