I was able to get the code built and working on a Fedora 12 system.
Initially I had the same error, but through some digging I found that I
needed to set the FREETYPE_ROOT variable to '/usr/' in the aggdraw setup.py
file. The latest freetype2 packages are already installed and all the
necessary libraries, includes, and code can be found within the /usr/
directory tree.
Thanks for the tip, Greg!
