here we explain how to compile nullsoft nsis and hfs plus tools on linux.
it's needed for windows installer and 

  1 Nullsoft NSIS Installer
  -------------------------

First, install scons tool : 
on mandriva : sudo urpmi scons
on gentoo   : emerge -auvDt scons

then execute the following : 

export NSIS_VER=2.39

cd ~
wget http://heanet.dl.sourceforge.net/sourceforge/nsis/nsis-$NSIS_VER-src.tar.bz2
wget http://heanet.dl.sourceforge.net/sourceforge/nsis/nsis-$NSIS_VER.zip

cd /usr/src
sudo tar xvfj ~/nsis-$NSIS_VER-src.tar.bz2
cd /usr/share/
sudo unzip ~/nsis-$NSIS_VER.zip
sudo ln -s nsis-$NSIS_VER nsis

cd /usr/src/nsis-$NSIS_VER-src
sudo scons SKIPSTUBS=all SKIPPLUGINS=all SKIPUTILS=all SKIPMISC=all NSIS_CONFIG_CONST_DATA_PATH=yes \
 APPEND_LIBPATH="/usr/local/lib" APPEND_CPPPATH="/usr/include" NSISDIR=/usr/share/nsis \
 PREFIX_CONF=/etc/nsis PREFIX_BIN=/usr/bin PREFIX_DATA=/usr/share/nsis \
 PREFIX=/usr/share/nsis

sudo scons SKIPSTUBS=all SKIPPLUGINS=all SKIPUTILS=all SKIPMISC=all NSIS_CONFIG_CONST_DATA_PATH=yes \
 APPEND_LIBPATH="/usr/local/lib" APPEND_CPPPATH="/usr/include" NSISDIR=/usr/share/nsis \
 PREFIX_CONF=/etc/nsis PREFIX_BIN=/usr/local/bin PREFIX_DATA=/usr/share/nsis \
 PREFIX=/usr/share/nsis install-compiler

  1 mkfs.hfsplus
  -------------------------

The kernel module hfsplus must be installed.

Download the following source from apple (need registration) : http://www.opensource.apple.com/darwinsource/tarballs/apsl/diskdev_cmds-332.14.tar.gz

Then execute the following :

wget http://www.mythic-beasts.com/resources/appletv/mb_boot_tv/diskdev_cmds-332.14.patch.bz2
tar zxf diskdev_cmds-332.14.tar.gz
bunzip2 -c diskdev_cmds-332.14.patch.bz2 | patch -p0
cd diskdev_cmds-332.14
make -f Makefile.lnx
cp newfs_hfs.tproj/newfs_hfs /sbin/mkfs.hfsplus
cp fsck_hfs.tproj/fsck_hfs /sbin/fsck.hfsplus
cd /sbin
ln -s mkfs.hfsplus mkfs.hfs
ln -s fsck.hfsplus fsck.hfs
