This is a very early alpha of ZFS on OSX, to be the next generation of MacZFS. Test this with the expectation of a kernel panic.
** zfs.kext depends upon spl.kext, so start with that repository.
It is tested primarily on Mac OS 10.8.4 and secondarily on 10.6.8, with the latest Macports.
See https://github.com/zfs-osx/ and http://MacZFS.org/ for more information. Note MacZFS's wiki on kernel development and panic decoding.

Please note that 'llvm-gcc' or 'clang' has to be used for compiling KEXTs. Pure 'gcc' will produce instable builds.
# ./configure CC=clang CXX=clang++
or
# ./configure CC=llvm-gcc CXX=llvm-g++
# ./autogen.sh
# ./configure CC=clang CXX=clang++ --with-spl=/path/to/your/spl
