Yes, ranlib made configure much happier. It got a little further.  
Then it couldn't find gd.h, so I included another path and it finally  
configured.

configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h

Unfortunately, make did not get very far

Thomas-Rikes-Computer:~/sage-1.3.6/spkg/build/dvipng-1.8 trike$ make

I'll consider this thread closed since we have solved the  
libkpathsea.a  problem. Thanks to everyone who helped. I really  
learned a lot in two days. I will still play around with trying to  
install dvipng-1.8, but the SAGE author William Stein has suggested  
some workarounds since dvipng-1.6 is already installed with MacTeX.  
It will be good to get back to just LaTeX and Mathematics for awhile.  
If you are interested in computer experimentation in mathematics I do  
recommend you look at SAGE (written in Python) which includes  
interfaces with  GAP, Maxima, Singular, PARI, Matplotlib, Numeric,  
Python, and IPython. It has a browser interface as well as the  
ability to interface with Mathematica and Maple. Sage objects can be  
included in LaTeX and evaluated interactively in the output. http://

Thanks again. Tom Rike
