XFree86-4 & xorg build errors

[Nutterpc]

Attempting to try to compile either xorg or free86 after
doing a fresh install, updating ports, and everything else,
then going to install the window manager, and each one (xorg
& xfree86-4) both emit the same error:

/usr/X11R6/lib/X11/doc/html:Permission Denied

It's stopping me from being able to get X up on screen atm,
and I'm trying all possible options I can think of

When someone has the chance to reply with help or a fix,
that'd be great :)

Cheers
