Re: [Discuss-gnuradio] Problem finding gnuradio libraries on Mac OSX 10.6

[Michael Dickens]

Hi Scott - You shouldn't need to set the DYLD path.  Have you verified that the 
file "/opt/local/lib/libgnuradio-core.3.5.2git.dylib" exists?  Did you use 
/opt/local for the MacPorts install?  I would -highly- recommend keeping 
MacPorts and any local installs separate -- e.g., use /opt/local for MacPorts 
and /usr/local for anything installed by hand.  You shouldn't need to do "sudo 
make" to get everything to compile, no matter if using CMake or GNU Autotools.  
All of this says to me that your OS install is odd. - MLD
