Ive just tried the world update on portage 1.8.5 and I noticed that it wants to go back to an older version of ssh, ie from 3.0.2 to 3.0_p1.
need to expand zeros for version comparison
I still have that Patch I made to fix this if needed.
pending a review of vitaly's code, this is fixed. Assigning to gbevin.
code reviewed and added to portage-1.8.6-r3
