You got errors when running apt-get install gnuradio? Can you please pastebin them somewhere? In general, you can and should use apt-get install if the version you get is "new enough" for your taste. > I tried this a couple of times with same result. > > I then tried to remove as much of this as I could and went down this road > $ git clone http://git.gnuradio.org/git/gnuradio.git > $ ./build-gnuradio FYI: build_gnuradio does the cloning for you. > And this seemed to work OK.

It seems like you're trying to import a really old flow graph. All of these blocks have been moved to a new sub-component (in this case, gr-blocks). When you start GRC, you can find all of these blocks in the sidebar. This way, you should be able to reconstruct your flow graph in no time.
