1. Thank you for your advice. I went through and changed ownership to my user 
name, and I will only use sudo for installation.
2. I still want to figure out why gr-howto-… is failing, but I have installed 
gr-modtool and will be using it.
        Does anyone know of a good tutorial for this package? I wrote my work 
function, but I'm not sure how to write a test.
3. I tried using ctest and got the following error:

It appears that qa_howto failed because of a missing module.
