Getting HOPS running via MacPorts.

0) get Macports.  I used the SnowLeopard dmg (1.9.2) downloaded from

    http://www.macports.org/install.php

    but there are Leopard and Tiger versions as well.  It also installs
    via a source tarball, but I haven't tried that.

    From the dmg, it installs the same way as other *.dmg packages do--and
    by default it goes into /opt/local (which is ok with me:  /opt has
    nothing in it on my mac).

1) The install process will modify ~/.bash_profile (if you already
    have one, macports saves it but you may wish to review the mods)
    by adding /opt/local/bin and /opt/local/sbin to your PATH.

    The main commands are similar to debian/rh/fink packaging commands
    via a command named "port":

    sudo port selfupdate	    # brings macports itself up-to-date
				    # apparently 1.9.2 is the latest
    port search <portname>	    # look for packages (or see their site)
    sudo port install <portname>    # to actually install something

2) MacOS doesn't have wget which I like for grabbing things from
    anonymous ftp.  (curl should be able to do it, but I don't know
    the proper incantation):

    port search wget
    sudo port install wget
    # required dependencies:
    # gettext expat libiconv gperf ncurses ncursesw libidn openssl zlib

3) You'll need an explicit reference to ghostscript as /usr/bin/gs

    sudo port install ghostscript
    # required dependencies
    autoconf help2man p5-locale-gettext perl5 perl5.8 m4 automake
    fontconfig freetype jpeg libpaper libpng libtool pkgconfig tiff
    xorg-libXext xorg-libX11 xorg-bigreqsproto xorg-inputproto
    xorg-kbproto xorg-libXau xorg-xproto xorg-libXdmcp xorg-libxcb
    python27 bzip2 db46 gdbm readline sqlite3 xorg-libpthread-stubs
    xorg-xcb-proto libxml2 xorg-util-macros xorg-xcmiscproto
    xorg-xextproto xorg-xf86bigfontproto xorg-xtrans xorg-libXt
    xorg-libsm xorg-libice

oops:

Ok, download the java developer package, install it, and try again

sudo port install ghostscript

    sudo ln -s /opt/local/bin/gs /usr/bin/gs

4) pgplot

    sudo port install pgplot

--->  Dependencies to be installed: gcc44 gmp mpfr

    Unfortunately this port sprays the various pgplot pieces into
    quasilogical places that HOPS doesn't know about, so, as root:

    cd /opt/local
    mkdir /opt/local/pgplot
    cd /opt/local/pgplot
    for l in ../lib/*pgplot* ; do ln -s $l . ; done
    ln -s ../bin/*pgxwin* .
    ln -s ../share/pgplot/* .

N) Grab Hops (3.3 is the current release via ftp--similar instructions
    most likely to apply to later HOPS releases).

    mkdir ~/HOPS
    cd ~/HOPS

    wget ftp://gemini.haystack.mit.edu/pub/hops/README-3.3.txt
    wget ftp://gemini.haystack.mit.edu/pub/hops/hops-3.3.tar.gz

N+2) Configure it...

    Follow the instructions as in the README; however a few configure
    arguments are needed:

    ../hops-3.3/configure LDFLAGS=-L/usr/X11/lib \
	PGPLOT_DIR=/opt/local/pgplot

    (The PGPLOT_DIR assignment is unnecessary if you've installed
    MacPorts in the default hierarchy under /opt/local.)
    
    Due to the way Apple hacked the gnu gcc compiler, the configure
    script will probably generate a number of annoying error messages:

	rm: conftest.dSYM: is a directory

    which you can safely ignore.  You should be in good shape if you
    then see:

      Configure passes sanity checks.

	 have_hops is true (required)
	 have_devel is false (optional)
	 have_gs is true (required)
	 have_x11 is true (required)
	 have_pgplot is true (required)
	 have_png is true (required)
	 have_difx is false (optional)
	 have_mark5 is false (optional)

    followed by messages about Makefiles created, and so forth.
    You can then proceed with

	make
	make install
	make check

    and the checks as described in the README.  Note that the
    install with put a source-able script hops.bash into your
    ~/bin directory should you have one.

    The 3.2 release requires <stdint.h> being included in the #else
    case of T1.h.  That was fixed in 3.3.  However other less
    obvious errors might still be present, so be ware....
