Understood. In Debian Squeeze the old TeXLive 2009 metapackage package 
is named "texlive". So it seems that "texlive", which is a metapackage 
for TeXLive 2009, is not really TeX Live despite the similarity of 
names ;-(.

Also understood.

Here I have a question. I logged out and back in, and now have the 
path /usr/local/texlive/2011/bin/i386-linux: defined _five_ times (as 
reported by $ echo $PATH). And this is not the path you just assumed 
it would be, although in fact describes my actual hierarchy. I assume 
there's nothing critically wrong here, but just need to be sure.

I'm not sure I understand. I apparently inadvertantly reinstalled 
texlive (2009), because I find I now have a /usr/bin/tex and 
directories such as texlive-base in /usr/share. But I gather this is 
not a problem as long as the path is set up right.

I'm confused. Here it seems you are telling me how to configure 
texlive 2009, when my goal is to configure TeXLive 2011. You seem to 
be telling me to su to # prompt, and then export the paths you 
suggest. However, if I do su, root already has that environment:

  # echo $PATH

I believe I understand how one can switch between TeXLive 2010 and 
2011 by changeing the path to one or the other, but texlive 2009 has 
no dedicated path, and so the executables are always accessible. I 
have this:

  # ls /usr/bin | grep tex

and yet

  # which tex
