as an interim measure, people are invited to try my standalone install
of pygist, which I've tested on Solaris and Linux.  It uses Konrad
Hinsen's compile.py and install.py to winkle out your --prefix and
--exec directories and fetch Makefile.pre.in and build gistCmodule.so
and arrayfns.so.  It is missing some of
the demos, which I need to tweak to remove PDB dependencies.  I'm up
against a grant proposal deadline, so this won't happen this week, but
feel free to try it and report your success/failure.

Here's the Readme, to be found with the rest of the package at:


http://www.geog.ubc.ca/~phil/python/gist.html

_________________________________________________________
This README explains how to install gist as 
a dynamically loadable library on Linux and Solaris
(and presumably other Unices).   
You should have received it as part of the 
tar file:
http://www.geog.ubc.ca/~phil/python/ubcgist.tar.gz


Installation requires that you have installed Python 1.5, 
Konrad Hinsen's distribution of Numerical Python and gist/yorick.  See
http://www.geog.ubc.ca/~phil/python/gist.html for the location of these
packages.


To make the library:

1) uncompress and untar ubcgist.tar.gz.  The resulting gist directory
   contains this README file, C code for gistCmodule and arrayfnsmodule,
   gistdemo.py (to test the plotting package) and a subdirectory
   called graphics, which contains gist.py among other things.

2) cd gist

3) create the file Setup, using either Setup.linux or Setup.solaris
as a template.  You need to supply the location of the Yorick
include files (-I/YORPATH/yorick/1.4/h) the library libgist.a
(-L/YORPATH/yorick/1.4/lib) and libX11.a  

4) type:

python compile.py
python install.py

with luck the files:

gistCmodule.so
arrayfnsmodule.so

have been copied into  EXECDIR/lib/python1.5/lib-dynload/, 
where EXECDIR is the directory given to python by

 ./configure --prefix=INSTALLDIR --exec=EXECDIR

5) copy the graphics directory to:

INSTALLDIR/lib/python1.5/

6) Edit your .cshrc file so that PYTHONPATH includes
   INSTALLDIR/lib/python1.5/graphics and
   INSTALLDIR/lib/python1.5/graphics/gist i.e:

     setenv PYTHONPATH .:/home/phil/lib/python:/home/phil/lib/linux/python:/home/phil/src.dir/python.dir/python-1.5/install/lib/python1.5/graphics:/home/phil/src.dir/python.dir/python-1.5/install/lib/python1.5/graphics/gist

7)  Test with:

python gistdemo.py


You should be able to step through about 20 plots demonstrating some
of gist's features.  For more documentation see:
