might be the problem.
Thanks.

Possibly Ubuntu sets up /usr/local to be regular-user
writeable, but that would be a horrible security flaw.
At least for my Ubuntu 12.04 /usr/local is owned by root:root with 0755
permissions and everything else would have given me nightmares ;)
Maybe you started the script with sudo, instead

All uhd_fft does is connect a USRP source to an FFT sink. Problems
