I was not clear.  On Mac OS X, the build (gcc) automatically uses 
libSystem.  It's the Mac OS X/Darwin version of libc, so I'm unclear as 
to why these were missed.  I'll review the log later, and see if I can 
track this down.

The build doesn't produce a gp-dyn, and we don't have 'ldd' (Mac OS 
X/Darwin uses 'otool' instead).  I've verified that there are versions 
of readline in /usr/local/lib (as above) and in /sw/lib, which wasn't 
searched (in /sw/lib, there are 4, 4.2, and 4.3).

I'll look further at these; it's possible that something in the .dylibs 
themselves is confusing the issue.
