[buug] Teaching myself Python, (&Gnuplot&Unix) not playing correctly

Johan, All,
PATH:
ssands$ $PATH
-bash:
/Library/Frameworks/Python.framework/Versions/2.6/bin:/bin:/sbin:/usr/bin:/usr/local/bin:/usr/sbin:
No such file or directory

This is one of my problems, is that I am uncertain where to place all the
various components of the software.

Gnuplot.app is in the applications folder (v4.2.5)

I also have in the site-packages folder, a folder labeled gnuplot-py-1.8
which contains:

computer:/Applications/Python_2.6/site-packages/gnuplot-py-1.8 ssands$ ls
ANNOUNCE.txt            LICENSE.txt             README.txt
doc                     gp_java.py              setup.cfg
CREDITS.txt             MANIFEST.in             TODO.txt
funcutils.py            gp_mac.py               setup.py
Errors.py               NEWS.txt                _Gnuplot.py
gnuplot_Suites.py       gp_macosx.py            termdefs.py
FAQ.txt                 PKG-INFO                __init__.py
gp.py                   gp_unix.py              test.py
Gnuplot.html            PlotItems.py            demo.py
gp_cygwin.py            gp_win32.py             utils.py

Also in the site-packages folder, is Gnuplot:

computer:/Applications/Python_2.6/site-packages ssands$ ls
Gnuplot                         gnuplot-py-1.8
numpy                           scipy-0.7.2-py2.6.egg-info
wxredirect.pth
README                          gnuplot_py-1.8-py2.6.egg-info
numpy-1.4.1-py2.6.egg-info      setuptools-0.6c11-py2.6.egg
easy-install.pth                nose-0.11.3-py2.6.egg           scipy

The Gnuplot folder contains:

computer:/Applications/Python_2.6/site-packages/Gnuplot ssands$ ls
Errors.py               __init__.py             gnuplot_Suites.py
gp_java.py              gp_unix.py              test.py
Errors.pyc              __init__.pyc            gnuplot_Suites.pyc
gp_java.pyc             gp_unix.pyc             test.pyc
PlotItems.py            demo.py                 gp.py
gp_mac.py               gp_win32.py             utils.py
PlotItems.pyc           demo.pyc                gp.pyc
gp_mac.pyc              gp_win32.pyc            utils.pyc
_Gnuplot.py             funcutils.py            gp_cygwin.py
gp_macosx.py            termdefs.py
_Gnuplot.pyc            funcutils.pyc           gp_cygwin.pyc
gp_macosx.pyc           termdefs.pyc

Best regards,

Steve
