title: Will upgrading fix the FreeBSD 8.1 portstree?
body: <p>I have a machine running FreeBSD and the ports tree is accidentaly updated to one of FreeBSD 8 stable. The problem is that my FreeBSD 8.1 is not configured to use PKG for packages so I cannot update or install packages.</p>
  
  <p>I want to upgrade the machines FreeBSD but get the ports tree in working order before I do that. </p>
  
  <p>It seems the only solution is installing an old 8.1 version of the ports tree, but I cannot find any. 
  Can someone tell me where to find this?</p>
  
  <p>Would upgrading to the lastest stable version 8 also solve my problem?</p>
