Comment(by blb@…):

 Currently, the selfupdate procedure uses the current owner of the install
 prefix (/opt/local by default) to be the owner of the updated install (see
 [browser:trunk/base/src/macports1.0/macports.tcl?rev=50868#L2104
 macports.tcl]).

 Perhaps there should be a check to make sure these ids exist first, since
 apparently some systems don't have a group 501?
