Nicolas: Yes, this produces a much leaner library. The MacPorts  
approach is nearly four times the size of a manual build!

Thank you or looking at this. I see now I need to focus on aclocal.m4  
(to supply the correct SO_OPTS) and src/Makefile (to construct the  
correct SONAME). I'll report back if I come up with something.

Someday I will understand GNU configure:-)
