[OS X TeX] MacPorts and TeX Live

[Enrico Franconi]

Hi,
I have TeX Live installed by downloading the distribution and updating it via the TeX Live Utility.
When I try to install packages from MacPorts needing TeX Live, MacPorts does not realise that I have already TeX Live installed, and it will download and recompile everything from scratch.
Is there a way to tell MacPorts to use the already installed TeX Live distro?
cheers
