Mac install ignores homebrew install of Node.js #167
Description
When using "curl -kL http://get.virtual.wf | sh" as the installation method, Node.js is installed with symlinks from /usr/bin/... to $HOME/.vwf/.node/bin/...
This action does not take into account a homebrew installation of Node.js or other as well as multiple users on the system not having access to your home directory since it is symlinking there.
The installer should ask if you want Node.js installed and recognize an existing installation. It should also use /usr/local/bin, but it may need to create it or just ask the user to put it in their PATH.
