I don't know about your specific question, but in both sets of output  
you quote above I see

-L/usr/local/spidermonkey/lib/

and

-L/sw/lib/firefox2

So presumably you have libraries in /usr/local and /sw, neither of  
which is recommended or supported when using MacPorts. Please try  
again after you have removed or moved aside /usr/local and /sw.
