>> Attached as a zip is the result of installing from sox-14.4.0.tar.gz (after errors resulting from spaces in the path to the sources were fixed), trying to test, and trying to run. The text output in this file is the result of typing

The mysteriously-referenced library does exist at /usr/local/adacore-gnat-2010/lib/libgomp.1.dylib.

Could it be that you should do this prior to ./configure...
