Try following the download page:

http://gnuradio.org/redmine/projects/gnuradio/wiki/Download

Specifically, delete your gnuradio directory and run the git clone this way:

git clone --recursive http://git.gnuradio.org/git/gnuradio.git

That should make sure you've properly pulled the volk submodule as well.
