tex wanting to install even though it's not outdated

[John Owens]

classico 8914$ port outdated
No installed ports are outdated.
classico 8914$ sudo port upgrade installed
--->  Extracting texlive_texmf-full

So I'm using MacTeX (in /usr/texbin) for my TeX distribution
now, and have set binpath in macports.conf accordingly. This
works fine. How can I keep "port upgrade installed" from
wanting to install a macports texlive? (Perhaps one of my
ports depends on it; how could I figure that out?)
