Okay, this is what I get

The "disabled prebinding" problem re-appears. "fluidsynth.la" is 
actually a script generated by libtool and not an object file (see 
below).

I have to convert or use this script to create an object file it seems 
or at least have some sort of "libfluidsynth" static or dynamic library 
before linking can progress further. (see the contents of the src 
directory below.) I am contemplating using the object file link editor 
"ld" for this. (The man page for "ld" is particularly long.) Any ideas 
how I could do this?

No, I did not enable neither alsa, ladspa nor oss. On the other hand, 
according to the configuration summary, MidiShare is enabled (check my 
e-mail 8th March, 2004). I also noticed that the new version of 
MidiShare(1.87) no longer includes the "msSynthDriver" which is the 
fluidsynth driver and the libMidiShare.1.8.6.dylib is no longer present 
in /usr/lib !!! though the msMidiDriver and msQTDriver fortunately 
are.:) MidiShare now exists as 
"/System/Library/Frameworks/MidiShare.framework".

If I could play soundfont files from my MIDI keyboard controller that 
would be a great place to start.  I could leave MidiShare on the back 
burner for a little while. I guess we'll tackle one problem at a time.

Will do when the fluidsynth binary is ready.
