Comment:

 Unfortunately a lot of users don't really know what they're doing, and
 will try to do things that are prone to cause problems. We believed
 setting the MacPorts prefix to /usr/local was one of those things, so we
 blocked it.

 If you believe /usr/local is a viable prefix for MacPorts you should
 discuss this on the [http://lists.macosforge.org/mailman/listinfo
 /macports-users/ macports-users mailing list]. (A ticket is not a good
 place to have a discussion.) I don't remember all the reasons why we
 decided to block /usr/local, but if you've been using MacPorts in
 /usr/local successfully for 15 months without problems that's good to
 know, and it would be interesting to hear (on the mailing list) how many
 and what kinds of ports you've been installing.
