My understanding of PATH is that it defines directories in which

I personally prefer to place the /opt directories before the
system's /usr and /bin directories in the path, so that if I install
newer versions of something using MacPorts which the OS already
provided older versions of, the new versions get used when I ask for
them, not the old ones.
My path, for your info and for comparison, is "/Users/rschmidt/bin:/

Well, it told you the MacPorts base software was up-to-date. But
apparently you had some installed ports, including libxml2, which
were not up-to-date. "port outdated" will tell you which installed
ports have newer versions available, and you can then upgrade them.

Not sure why it did that, but your instinct was a good one: perhaps
this was because your libxml2 was old and buggy and a new version
would fix it.

As "port installed" will show, libxml2 is already installed,
therefore you get an error when you try to install it again. You
needed to have either uninstalled (or at least deactivated) libxml2
first ("port uninstall libxml2", or "port deactivate libxml2"), or
what you probably meant to do is just upgrade libxml2 ("port -u
upgrade libxml2" -- the -u flag tells port to uninstall the old
version of the port right before it installs the new version; if you
don't use -u, it will just deactivate the old version but keep it
installed so you can activate it again later if you want).
