Installation instructions for GhostScript on MacOS X

Ghostscript 7.00 and ghostscript 6.50 work on Mac OS X but might produce PDF
that is not displayed correctly by Mac OS X 10.1, though it is displayed
correctly by Acrobat 4 and 5.

Step 1. Get files

You need the following files:
	ghostscript/7/ghostscript-7.00.tar.gz
	ghostscript-7.00libpng.tar.gz
	ghostscript/7/gs7.00.macosx.patch
	libs/jpegsrc.v6b.tar.gz
	libs/libpng-1.0.10.macosx.patch
#	libs/zlib-1.1.3.macosx.patch
#	libs/zlib-1.1.3.tar.gz
	ghostscript/ghostscript-fonts-std-6.0.tar.gz
	ghostscript/ghostscript-fonts-other-6.0.tar.gz

From now one, I assume you have these available in some working directory.
I assume from now on that this working directory is called ${WD}. If you
want to literally execute the statements below, go to the working directory
and execute:

	setenv WD `pwd`

Note: sometimes under MacOS X, you need to select one line at a time from the
execute statements below as copy/paste does not preserve end of line while
copying.

Step 2: Create directories

GhostScript needs the availaibility of the osurces of above libraries. Therefore, this
setup assumes that you unpack the sources in /usr/local/src just as defined below.

Execute:
	sudo -s
	mkdir -p /usr/local/bin
	mkdir -p /usr/local/lib
	mkdir -p /usr/local/man/man1
	mkdir -p /usr/local/include
	mkdir -p /usr/local/share/ghostscript
#	mkdir -p /usr/local/src/zlib
	mkdir -p /usr/local/src/libpng
	mkdir -p /usr/local/src/jpeg
	mkdir -p /usr/local/src/gs
	exit

Step 3: Unpack sources and apply patches

Assuming the files mentioned under step 1 are in your current directory (with
subdirs), execute:

	sudo -s
	(cd /usr/local/share/ghostscript; gnutar zxvf "${WD}"/ghostscript/ghostscript-fonts-std-6.0.tar.gz)
	(cd /usr/local/share/ghostscript; gnutar zxvf "${WD}"/ghostscript/ghostscript-fonts-other-6.0.tar.gz)
#	(cd /usr/local/src/zlib; gnutar zxvf "${WD}"/libs/zlib-1.1.3.tar.gz)
	(cd /usr/local/src/libpng; gnutar zxvf "${WD}"/ghostscript/7/ghostscript-7.00libpngtar.gz)
	(cd /usr/local/src/jpeg; gnutar zxvf "${WD}"/libs/jpegsrc.v6b.tar.gz)
	(cd /usr/local/src/gs; gnutar zxvf "${WD}"/ghostscript/7/ghostscript-7.00.tar.gz)
	(cd /usr/local/src/gs/gs7.00; mkdir obj bin)
	(cd /usr/local/src/libpng; patch -p0 < "${WD}"/libs/libpng-1.0.10.macosx.patch)
#	(cd /usr/local/src/zlib; patch -p0 < "${WD}"/libs/zlib-1.1.3.macosx.patch)
	(cd /usr/local/src/gs; patch -p0 < "${WD}"/ghostscript/7/gs7.00.macosx.patch)
	exit

Step 4: Compile and install the libraries

From the working directory, execute:

	sudo -s
#	(cd /usr/local/src/zlib/zlib-1.1.3; make install)
	(cd /usr/local/src/libpng/libpng-1.0.10; make install)
	(cd /usr/local/src/jpeg/jpeg-6b; ./configure; make install)
	(cd /usr/local/src/gs/gs7.00;  make install)
	strip /usr/local/bin/gs
	exit

DONE!

Thanks to Richard Koch for bugfixes.
