Thanks DavidW for the very informative link!
I think my python installations may be a bit "wonky." Here's what I
get when I enter:
Macintosh-4:~ gary$ ls -l /Library/Frameworks/Python.framework/
Versions/
total 8
drwxr-xr-x 7 root wheel 238 Mar 11 2008 2.3
drwxr-xr-x 11 root wheel 374 Mar 11 2008 2.5
drwxrwxr-x 10 root wheel 340 Oct 1 16:52 2.6
lrwxr-xr-x 1 root wheel 3 Dec 28 17:19 Current -> 2.6
that looks ok. It's possible to maintain more than one version
simultaneously.
Then if you wanted to use v2.5 you just change the Current symlink to
that in the Versions dir, as above.
Note that each version has its own 3rd party packages directory. I'm
using 2.5 so for me it is at
/Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/
site-packages/
and what I get when I enter:
Macintosh-4:~ gary$ ls -l /System/Library/Frameworks/
Python.framework/Versions/
total 8
drwxr-xr-x 7 root wheel 238 Mar 11 2008 2.3
drwxr-xr-x 11 root wheel 374 Mar 11 2008 2.5
drwxrwxr-x 10 root wheel 340 Oct 1 16:52 2.6
lrwxr-xr-x 1 root wheel 3 Dec 28 17:19 Current -> 2.6
This is where the apple distributed directories are.
Not sure why. Perhaps you;ve kept them (up to 2.5.1, I think) as a
result of OS upgrades.
I think most macpython users don't use them, unless you're
specifically needing to check that something runs on a default sys.
setup,
preferring, instead, to use those in /Library/Frameworks/
Python.framework/Versions/.
It appears to me that these are identical, though the /System/
Library/ directory is supposed to be where Apple installs it's apps.
Some how I must have done something kinda screwy.
Perhaps. I don't think apple has distributed a v2.6 yet.
Also, it's puzzling to me that "Current" in both cases is linked to
2.6, yet when I enter "python" from my home directory, I'm getting
Python 2.5.1.
My guess is that it's loading the apple distributed one in System/
Library/Frameworks/Python.framework/Versions/2.5
try, at the unix prompt
% which python
You should also check whether there is a shell variable $PYTHONPATH --
% echo $PYTHONPATH
depending on the results of those queries, you can force it to use a
particular one.
Say which shell you're using (bash?, sh? csh?)
David.
Last puzzlement, When I enter "python" from my home directory, how
does it know which python to reference? There must be some way it
chooses one python over another.
What's the best way to sort my seemingly confused system out?
Thanks much again,
Gary

Hi Gary - welcome to the list.
This is a frequent question so a search of the archive might help,
but here's my explanation:
