Comment(by ecronin@…):

 D'oh forgot about this ticket until I saw the commit go across this
 morning...  Two nits about the check block:

 * Doing the check in pre-extract is nice from a fail-early standpoint, but
 since it's easily fixable (not a "this will never work on your computer
 and you just wasted hours building things" errir) I think it belongs as
 pre-activate to handle the permissions changing between the check and when
 you finally activate, either because you did 'port deactivate' or because
 you installed from an archive which never ran the check on your machine to
 begin with

 * You also need to check that no part of the path is a+w like comment 1
 part 6 says.
