Understanding the depends syntax

[Adam Mercer]

Hi

I'm trying to install the gnuplot port and am running into an issue
relating to TeX. The gnuplot port depends on "bin:tex:teTeX" which, if
I understand this correctly, checks for a binary "tex" in the $PATH
and if it can't find it installs the teTeX port.

I have TeX installed with MacTeX 2007:

$ which tex
/usr/texbin/tex
$

yet when I try to install gnuplot, it starts installing the teTeX port
- I don't want to have two different TeX implementations.  Is this the
expected behaviour? And is there a way round this?

Cheers

Adam
