I'm not sure I understood what your comment here is, but to explain my point again, there is no reason to use a gz distfile when a bz2 distfile is available, because bz2 compresses better than gz and tools for decompressing bz2 files are built into Mac OS X. That is why I switched the distfile type here. It has nothing to do with any GSoC project nor with compiling vs downloading binaries.

xz is an even better (smaller) compression format than bz2 so it's even more preferred, except that in this case the xz port can't itself use an xz distfile because then the xz port would have an extract dependency on itself.
