Build-gnuradio fails on Mint Olivia 15

Tried building GNUradio on Mint Olivia 15/64bit using the build-gnuradio
script from www.sbrac.org. I get the following error:

E: Unable to locate package python-gnuradio*
E: Couldn’t find any package by regex ‘python-gnuradio*’
Your Mint release must be at least Linux Mint 11 to proceed

I edited the line:
case grep RELEASE /etc/linuxmint/info in
11|12|13|14)

to

case grep RELEASE /etc/linuxmint/info in
11|12|13|14|15)

But the same error still appears.

So is this a repository issue with python-gnuradio packages?
