How to update latex packages in Xcode?

I think that that the latex installed on my Leopard is through Xcode.

However, some of the latex packages such as natbib is outdated. I'm wondering how to update all the latex packages?


$type latex
latex is /opt/local/bin/latex
$type pdflatex
pdflatex is /opt/local/bin/pdflatex

You could install MacPorts and install the version available through that if they are available. Take a look at the ports available to see if what you need is available.
