Yeah, but plpgsql.so is mentioned nowhere on your command line.
I'm not too sure about the dynamic-linking rules on OS X, but I'd not be
surprised if you need to provide a reference to plpgsql.so in its final
installed location (ie, a reference to it in the build tree may appear to
link and then fail at runtime).
