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.

FYI: build_gnuradio does the cloning for you.

You can't call it grc on the command line (there was a package conflict
a while back).

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.
