Ha, well, I guess dppc was right . . . I tried to select a font that appeared as an imported bitmap, and once selected, the window changed to only include an option for size, which was unselectable. And the window can't be dismissed. Even after relaunching the Unity project, it is still there. So, yes, the compile dylib is faulty and shouldn't be used.
As I said, I myself do not possess the expertise with XCode to create the library, so will have to use the old-skool BMGlyph approach at this point.
