We should define what it means for PWD to work.  Using the ZSH shell:

% echo `/bin/pwd`
/scratch/bfriesen/build/GraphicsMagick-1.1-16-static

% echo `pwd`
/home/bfriesen/build/GraphicsMagick-1.1-16-static

% echo $PWD
/home/bfriesen/build/GraphicsMagick-1.1-16-static

Note that only /bin/pwd revealed the true path, but the shell's notion 
of the path is more pleasing to me since it is reporting how I got to 
the working directory and nicely hides that there was a symbolic link 
involved.
