[Discuss-gnuradio] Raspberry PI 2 build failure

[Ron]

Hello,

I have been attempting to build gnu radio on a Raspberry PI 2 running 
Debian Wheezy.  I believe I have properly built and installed the latest 
releases of the gnu radio dependencies. However the gnu radio build 
fails with the following:

It appears there is an issue with neon support.
Thanks,
