Re: [Discuss-gnuradio] GNU Radio and OS X installation - path problem?

Hi Fabrizio - Glad to hear you had success using MacPorts to install  
GNU Radio on your 10.5 box.  That's the goal!

The install guide was written for when one installs GNU Radio from  
source by hand, not using MacPorts.  I think that, so long as you've  
done:

sudo port install python_select
sudo python_select python26

then I don't think you need that "if" statement at all -- it's  
designed to make sure the default install ${prefix} for GNU Radio (/ 
usr/local) is included in the PYTHON search path.  Since you installed  
from MacPorts, the ${prefix} is /opt/local, which should be covered by  
previous lines in the script:

setenv PYTHON_VERSION `python -V |& sed -e 'address@hidden@ @2' | awk '{ print  
$2 }'` setenv
PYTHON_ROOT `which python | sed -e 's@/bin/python@@g'` setenv PYTHONPATH
${PYTHON_ROOT}/lib/python${PYTHON_VERSION}/site-packages

You might try commenting out the whole "if" statement (then "source  
~/.bashrc") & seeing if GNU Radio still works. - MLD
