Installation issues on Mac oSX El Capitan

[samganesan]

The lovely folks at Apple have made a dramatic change to the OS in El Capitan. They have taken away write privs even for root user to the /usr /bin and a couple of other directories under the name of protecting the users form themselves!!!! So the node installation symlink fails ... I am hacking the install script right now to mke it check to see if node exists already in the path etc. The otehr thing I will work on is to make it completely user space but it will take some time... since this is my late night project.
