When I got to the step which was supposed to let me choose where to install the  jdk, I did not see any control for configuring this location or any indication of where the files would be dropped. I continued with the installation, nonetheless. Afterward, I was not able to find the installation with this command:

The JDK must go into /Library/Java/JavaVirtualMachines. We do this because doing so will make it the default JDK for all of the command-line tools.

Why do you want to put it into a custom location?  Java VMs on the Mac have been installed into this location for some time now. 

I do have a to-do item to write up some instructions on how to verify that you have JDK 7 and that it is the default JDK, but just open up a Terminal window and type 'java -version'.  /usr/libexec/java_home will tell you, too.
