Selecting PHP command line version on HostGator shared host

This took me a while to find, so I'm saving it somewhere I can find it again.

The easy way to select the PHP version used for web applications is to use the CPanel configuration tool. However, that doesn't work if you're using SSH and need PHP on the command line. Also, on HostGator, you can't create a symlink outside of your directory (such as to the global php).

Fixing features for hotfolder

Here is some documentation about the process I used to solve some issues with hotfolder and the features module. I was doing this partly through the web interface and partly through a console, so this is a reconstruction of what I remember and the console log. 


I was getting the following error message when I tried to check hotfolder watches (see
