Link issue

[Adam Dershowitz]

I figured out the solution, and other people could run into it, so I  
figured I would pass it on.
It was not actually a macports problem.  But it seems that something  
from my old computer was being cached, even after doing make clean and  
a new cmake.   I found that going back to the original source code and  
then doing a cmake and make did the job.
My guess is that it was CMakeCache.txt that was not being regenerated.
Anyway, just a caution about odd link errors after upgrading from 10.5  
to 10.6.
