Awesome, thanks for the report Alan, and thanks Michael for the package. Happy to incorporate any required changes.

Michael, Bastian
Many thanks for your help, the macports method has worked perfectly and I now have a working gr-air-modes with the rtl-sdr dongle.

One can tweak the DYLD manager behavior during runtime via various DYLD_* variables < https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/dyld.1.html > ... I encourage folks to set these variables just for a specific execution, e.g,:

This port should be live by around 11 AM US/Eastern this morning. You'll want to "sudo port sync" at a minimum; "sudo port selfupdate" is almost always better.

This, in theory, allows the libraries using @rpath to be embedded within an application by setting the @rpath to be the absolute path to where those libraries are actually located.]
