New RSYNC for Mac Extended Attributes

If you want to rsync files between Mac's you will need a patched version of rsync. This will preserve the "extended" attribute stuff.

Apply patches relevant to preserving Mac OS X metadata
patch -p1 patch -p1
Configure, make, install
(note: creation times are not preserved in x64, so…)
./prepare-source
CFLAGS=-m32 CPPFLAGS=-m32 CCASFLAGS=-m32 ./configure
CFLAGS=-m32 CPPFLAGS=-m32 CCASFLAGS=-m32 make
sudo make install

Verify your installation
rsync --version

By default, rsync will be installed in /usr/local/bin. If that isn't
in your path, you will need to call your new version of rsync by its
absolute path (/usr/local/bin/rsync).
