portupgrade fails on every port, undefined method 'each' for nil:NilClass

[Akinori MUSHA]

Hi,

I have just committed a fix against the "undefined method `each' for
nil:NilClass" error that occurs typically when BEFORE_DEINSTALL is not
defined in pkgtools.conf.  Add "BEFORE_DEINSTALL = {}" to your
pkgtools.conf and pkg_deinstall will start working again.

For the "undefined method `>' for #<Array:0x8907500>" error, I still
have no idea.  Could you try again with a vanilla pkgtools.conf?
