+Prerequisites and instructions for using crosstool-NG for building a cross
+toolchain on MacOS as host.
+
+0) Mac OS Snow Leopard, with Developer Tools 3.2 installed, or
+   Mac OS Leopard, with Developer Tools & newer gcc (>= 4.3) installed
+   via macports
+
+1) You have to use a case sensitive file system for ct-ng's build and target
+   directories. Use a disk or disk image with a case sensitive fs that you
+   mount somewhere.
+
+2) Install macports (or similar easy means of installing 3rd party software),
+   make sure that macport's bin dir is in your PATH.
+   Furtheron assuming it is /opt/local/bin.
+
+3) Install (at least) the following macports
+   ncurses
+   lzmautils
+   libtool
+   binutils
+   gsed
+   gawk
+   gcc43 (only necessary for Leopard OSX 10.5)
+
+   On Leopard, make sure that the macport's gcc is called with the default
+   commands (gcc, g++,...), e.g. via macport gcc_select
+
+4) run ct-ng's configure with the following tool configuration
+   (assuming you have installed the tools via macports in /opt/local):
+   ./configure --with-sed=/opt/local/bin/gsed           \
+               --with-libtool=/opt/local/bin/glibtool   \
+               --with-objcopy=/opt/local/bin/gobjcopy   \
+               --with-objdump=/opt/local/bin/gobjdump   \
+               --with-readelf=/opt/local/bin/greadelf   \
+               [...other configure parameters as you like...]
+
+5) proceed as described in standard documentation
