Component:  ports     |    Version:  2.2.0

----------------------+--------------------------------
 upon installing macports, i get the following error, which im having a
 hard time resolving:
 invalid command name "mport_filtervariants"
     while executing
 "mport_filtervariants [array get requested_variations] yes"
     ("uplevel" body line 33)
     invoked from within
 "uplevel 1 $block"
     (procedure "foreachport" line 18)
     invoked from within
 "foreachport $portlist {
         set target $action

         # If we have a url, use that, since it's most specific
         # otherwise try to map the ..."
     (procedure "action_target" line 7)
     invoked from within
 "$action_proc $action $portlist [array get global_options]"
     (procedure "process_cmd" line 92)
     invoked from within
 "process_cmd $remaining_args"
     invoked from within
 "if { [llength $remaining_args] > 0 } {

     # If there are remaining arguments, process those as a command
     set exit_status [process_cmd $remaining..."
     (file "/opt/passcal/other/bin/port" line 3695)

 Is this because I have other software installed in /opt/local, where
 macports wants to live?
 If so, should I uninstall, then re-install in a new location - or will i
 run into problems if macports is not in /opt/local?
