Why XFree86 being installed ?

[Mark Hattam]

Another couple of hours and I found that XFree86 failed ... so now 
what happens? I don't understand the error or know what to do to fix 
it.




The following installed ports are outdated: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

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
