/usr/X11R6 exists, but it is not a symlink. Installation cannot proceed.
This looks like an incompletely removed old version of X.  In the current version, /usr/X11R6 must be a symlink if it exists at all.Please read /usr/ports/UPDATING (entry of 20070519) for the procedure to upgrade X.org related ports.*** Error code 1
