 It has a function "group_exists" and if it exists it is supposed to be 
 listed in +PREEXISTING. I see you have those above.
 
 That file should contain the name of package that created it.
 
 Looks like the problem is in CHECK-REMOVE action in 
 mk/pkginstall/usergroup -- it doesn't check the +PREEXISTING.
 
 I think it could still give the current message plus mention that the 
 group (or user) existed before any package was installed.
