Struggling to understand WHY this is happening. I have installed gnu radio on my MacBook Pro with no issues, but the install on the iMac 27" is not so smooth. HERE is what I am getting as output from the install (below) - it is import to not that gcc, Xcode and python both 2.7 and 3 are installed. BUT I'm at a loss as to why. APPRECIATE any help.
Clintons-iMac:~ clint$ sudo port install gnuradio
