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:

Errors while running CTest

----------

It appears that qa_howto failed because of a missing module.

It looks like you're just missing where libgnuradio-core is installed. Make sure you installed GNU Radio, and then set LD_LIBRARY_PATH to point to the location of the installed libraries (/usr/local/lib by default unless you've changed the install prefix).
