Hi, Michael, I'm thankful for what you've done to Mac users. Before this
port, building GNU Radio was really distressing and normally I just gave
up after several failed builds and use GNU Radio in Linux. 

Well, I tried to do a clean install MacPorts after this post. This time,
after MacPorts is installed, gcc 4.7 was installed first and used as
default compiler. Then I install every packages that gnuradio depends
with gcc 4.7. When I try to use gcc 4.7 to compile gnuradio with the
following command:

sudo port install gnuradio +docs +grc +orc +python27 +qtgui +sdl +swig
+uhd +wxgui configure.compiler=macports-gcc-4.7

The build was failed. And then I tried gcc 4.5 and it failed.  Only when
I use llvm-gcc-4.2 would give me a successful build. When I run
gnuradio-companion, I got this message:

If I run the following command:
sudo port -d configure gnuradio +docs +grc +orc +python27 +qtgui +sdl
+swig +uhd +wxgui configure.compiler=macports-gcc-4.7

The messages for VOLK part is:

For the command:
sudo port -d configure gnuradio +docs +grc +orc +python27 +qtgui +sdl
+swig +uhd +wxgui configure.compiler=macports-gcc-4.7

The difference seems to be AVX, and my configuration is listed below:
CPU: Quad-core Core i7, Ivy bridge architecture
OS: MacOSX 10.8.2
MacPorts version: 2.1.2 with latest sync on January 22
gcc version 4.7.2 (MacPorts gcc47 4.7.2_2) 
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)


Thanks in advance.
