Hi Adeel,

Ben Reynwar pointed this out to me yesterday: gr_modtool.py needs Python
2.7. I argued that anyone using the CMake version of the blocks would
have access to 2.7... guess I was wrong.
I'm afraid I can't post a fix to this right now (would mean some
rewriting), but I'll add a version check so the error message becomes
more useful.
