These dependencies are automatically detected from the URL, so declaring
them is redundant. If these formulae ever get a head or devel spec, then
explicit xz deps would need to be re-scoped appropriately. Thus we
should remove them.
Update gcal to version 3.6.2
Add the `xz` dep to decrease the download size and mirror load.
Add `--disable-dependency-tracking` because it's an option now.
Tested on Lion with clang and llvm-gcc from XCode-4.3.2.

It seems that the main GNU download site has issues in some places
outside the U.S., so we'll use the provided "ftpmirror.gnu.org" to pick
a nearby mirror.
