Hi Michael,

I didn't realize rtl-sdr was in macports, so I installed both of them
from source. It should be fine from macports though as long as it
doesn't get too old compared to gr-osmosdr. In order to have
gr-osmosdr installed in /opt/local I use:

$ cmake -DCMAKE_INSTALL_PREFIX=/opt/local ..

Be sure to uninstall the other first - having multiple copies of the
same library installed is very bad.

After installing rtl-sdr and gr-osmosdr I could compile gqrx but to
make it run I had to copy the rtl-sdr and gr-osmosdr libraries to the
same directory where gqrx.app was located. I suppose there is
something incorrect with the linker commands - I didn't have time to
look at it.

I only installed the minimal gnuradio whithout python and
gnuradio-companion. You probably need to add a path to the grc
configuration (I believe it's explained in the wiki).
