In the initial build, I used a single binary for Tiger and Leopard, and stripped out the 64bit stuff when installed on Tiger. Not only was that part a bit of a nuisance, but the compilation an assembly of the binaries was quite a hassle.
This rebuild uses separate binaries built specifically for each system version, so the installers are a bit larger.
I also cleaned up a few installer issues.
The UnixImageIO framework has been updated with libpng 1.2.23, giflib 4.1.6 and updates to libtiff to take care of a bug with LZW and overviews.
