Why XFree86 being installed ?

[Mark Hattam]

Just did a selfupdate and an upgrade of outdated ports ... as 
php5.2.3 came along ... the Powerbook has now been spent the past 2 
hours building XFree86 ... why??? And at the rate of it eating disk 
space, I fear it's going to fail before it finishes.

I obviously didn't need XFree86 with the outgoing versions of expat, 
freetype, pcre and php5 ... so why is it now a prerequisite?

The following is the Terminal output which has all been produced 
without intervention since the sudo port upgrade outdated instruction.




The following installed ports are outdated:
expat                          2.0.0_1 < 2.0.0_2
freetype                       2.3.4_0 < 2.3.4_1
pcre                           7.1_0 < 7.1_1
php5                           5.2.2_0 < 5.2.3_0
powerbook:~ user$ sudo port upgrade outdated

Error:
                     You have an Apple X11SDK installation already.
                         MacPorts will not overwrite it.

                     If you wish to use Apple X11,
                         install it from your MacOSX install disc.

                     If you really want to use XFree86 instead,
                         please move it aside first :

                             sudo mv /usr/X11R6 /usr/X11R6.apple
