Edward,
thanks for the reply. I'm going to not worry about exposing my
ignorance in what follows :-)
I ought to have specified that I did indeed think to invoke a new
shell after I made the changes. However, trying (2) and (3) as you
specified shed some light.
Early on, (probably miss-)following something I read on the net, I'd put
a block into my .bash_profile that read:
if 1; then
somestuff
Trying (3) gave
[EMAIL PROTECTED]:~$ . .bash_profile
bash: 1: command not found
Commenting out the bad block in .bash_profile, if I open a shell and
things are somewhat better.
Only somewhat, as if I open a brand new shell:
[EMAIL PROTECTED]:~$ python
Python 2.4.2 (#2, Sep 30 2005, 21:19:01)
[GCC 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu8)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

So, it seems that I currently have to invoke '. .bash_profile'
manually with each new shell opened for this to have effect. (Trained
by Bill, I even rebooted to be sure that the invocation of
'. .bash_profile' is needed.)
But, still it is closer :-)
I still haven't managed to coerce lines in /etc/profile exporting
PYTHONPATH to have an effect.

I didn't mean to suggest bruno was wrong, but instead that perhaps
ubuntu was a distro falling under his phrase:

such that the instructions he gave would not work without
modification. Apologies if I gave a different impression.

Thanks for the suggestions. With luck, I'll get the remaining issue
sorted. Thanks for the help,
