port_cutleaves

[Scott Haneda]

My first time using port_cutleaves:

    $port_cutleaves -b
    [Leaf 1 of 8] irssi @0.8.14_1+universal (active):
      [keep] / (u)ninstall / (f)lush / (a)bort: k
    ** irssi @0.8.14_1+universal will be kept.
    
    [Leaf 2 of 8] memtester @4.1.2_0+universal (active):

    ** mtr @0.75_0+darwin_10+universal will be kept.
    
    [Leaf 4 of 8] mysql5-server @5.1.44_0 (active):
      [keep] / (u)ninstall / (f)lush / (a)bort: k

    ** php5-mbstring @5.3.2_0+universal will be kept.
    
    [Leaf 6 of 8] php5-mcrypt @5.3.2_0+universal (active):
      [keep] / (u)ninstall / (f)lush / (a)bort: k

    [Leaf 7 of 8] php5-mysql @5.3.2_0+mysqlnd+universal (active):
      [keep] / (u)ninstall / (f)lush / (a)bort: k
    ** php5-mysql @5.3.2_0+mysqlnd+universal will be kept.
    
    [Leaf 8 of 8] port_cutleaves @0.1.2_0+universal (active):
      [keep] / (u)ninstall / (f)lush / (a)bort: k
    ** port_cutleaves @0.1.2_0+universal will be kept.
    

Both of those are normal software, active, and software I use on a regular basis, is this telling me it would remove it?  I do not understand why it was picked up in the list to begin with?  The man page is a little sparse, is there somewhere else I can go to read more about this tool/utility?

It even wants to offer to remove itself.
