I find that I can mix MacPorts and local installs just fine.  So, rtl-sdr using 
MacPorts and then gr-osmosdr into /usr/local should work fine with the proper 
environment variables settings.

That phase is called the "rev-upgrade" part.  "port" checks the newly installed 
libraries and those ports that explicitly depend on the just installed ports to 
make sure all references are valid (use "otool -L LIBNAME" to see what I mean). 
 When port finds broken references, it tries to reinstall the owning port.  
This has nothing to do with "ldconfig", but it does find and fix many errors 
that come up when handling installing projects.

I'm wondering where "libgnuradio-osmosdr.0.dylib" is located.  Usually this 
would be installed into ${prefix}/lib (so, /opt/local/lib in your case).

Your environment looks OK to me. - MLD
