Hi Mike,

Thanks for your help. As it turns out, I simply forgot to run the last
step that actually installs boost 1.51 after building it - that
explains why boost 1.52 got installed with uhd. I have now rebuilt
1.51, deactivated 1.52 and installed 1.51. Everything is ok now and I
installed gnuradio without problems.

I used: "sudo port install gnuradio +orc +uhd"
During configuration I saw the message:

WARNING: GNU Radio's VOLK component (which handles vector optimized
instructions and routines) compiles best when using GCC.  The selected
compiler is CLANG, which will result in a fully functioning GNU Radio
install but the VOLK component will not utilize the CPU's
capabilities.

Do you have any experience whether this can be a real performance
issue and what I can do to use gcc instead of clang?
