OK. I thought I knew what I was doing as I've messed around with my
installation for a long time. I looked at the following pages for a
guide on how best to do the update to 2009:


I wanted to get 2009 to live as the texmf-local tree of my current
installation, but that's probably what has caused the problems. I can
verify that I have two complete and working installations of TeXLive
(2007 from Ubuntu repositories and 2009 from ISO). However, I cannot
interact with them from the command line. There may have been issues
about which bits of the installation I performed as root (which steps
should be performed as root?). I would hope that a little jigging around
with configuration files would get everything working perfectly. Of
course, there's always the 'nuclear option' of removing the repository
packages and reinstalling from the ISO, but I shouldn't have to do that.
Can anyone suggest a way through this?
