[Discuss-gnuradio] Facing installation issues with GNUradio companion

I am trying to work with grc flow graphs. I downloaded the latest versions of gnuradio yesterday and I used Marcus's script to do it. I have not connected my laptop with USRP daughterboards. I am just trying to see if gnuradio companion was installed properly or not. I have ubuntu 11.10.

When I run the the dial_tone.grc program in gnuradio-examples/grc/audio folder, it gives me the following error:

./dial_tone.grc: line 1: syntax error near unexpected token `newline'
./dial_tone.grc: line 1: `<?xml version='1.0' encoding='ASCII'?>'

When I open a new terminal and type gnuradio-companion, a new GUI window comes up. However, the window only contains two blocks. When I click on the block group names (sources, sinks, etc.) in the right hand side, nothing shows up. I have attached a screen shot of the flow editor GUI with the email. Is it happening because the GRC requirements were not installed in my machine properly?

It's probably a very basic question :S . Any feedback will be very appreciated.
