FBSD 8 php 52 extensions dependency on X11 ???

[Alejandro Imass]

Hi,

Whilst installing some (many) of the php 52 extensions in a jail I
suddenly realized I was about to install X11 and a whole bunch of x11
related deps.
Can some kind soul explain to me which php 52 extension requires X11
??? Should it not say it EXPLICITLY??? !!!

FreeBSD 8.0-RELEASE
port: /usr/ports/lang/php52-extensions

Many thanks in advance,
