NPM Keeps Having Issues Finding My Node Path

Here's an example for me trying to install Node-Proxy because NowJS needs it:

sudo npm install node-proxy

    > node-proxy@0.5.2 install /home/jennifer/node_modules/node-proxy
    > make

I got this when trying to downgrade from node v0.6x to v0.4x. Fix was to run sudo make uninstall in the v0.6x directory and then reinstall v0.4x.
