Comment:

 You mean broken 15 months ago!

 Seriously, blocking a viable and used option is pretty damn retarded when
 you could print a warning during the configure process if you are that
 concerned. By your logic, you should add /System, /Library,
 /System/Library, /var, /usr, /bin, /sbin, /etc, /usr/bin, and a whole host
 of others to the blocklist because I just might decide to get crazy and
 shoot myself in the foot by setting any of those for the prefix. Better
 yet, just remove --prefix and hardcode it to install into
 /opt/local/macports/is/da/friggin/bomb/bitches and then you know it can't
 conflict with anything! I'm sure the users would love not having a choice
 because choices are hard, durrrr.


 P.S. You've wasted my time by making me backout this patch every time I
 update so I have no problem wasting your time by reopening a ticket to let
 you know how hard you suck.
