Looking at your version information below, you're running a very old
version of the GNU Radio Companion (grc 0.70). You'll need to update
it, which I think will solve your problem. I actually don't know if we
have a newer package of GRC out there, so you might have to
compile/install it yourself (Josh, let me know if I'm wrong about
this).
