Bugzilla Bug 16243

running emerge rsync on my systems recently warns me that a new versionf of 
portage is available.  Checking via emerge world -up" says that portage version 
2.0.47-r2 is installed, but 2.0.46-r12 is scheduled to be installed if I run "emerge world 
-u"  I've tried multiple rsync's to make sure I didn't sync from an out-of date mirror. Still 
get the issue.  decided NOT to re-emerge an older version of portage for fear that it 
might cause more issues.   
 
does portageand your rsync system use some sort of check-pointing to determine how 
far out ofa data a mirror is with the central repository (like cvs) ? Waht happens when 
someone rsync's to a mirro that is behind the times? (slow links or server misconfig) 
 

Reproducible: Always
Steps to Reproduce:
1.emerge rsync 
2.emerge world -up 
 
Actual Results:  
"emerge" displays: 
 [ebuild    UD] sys-apps/portage-2.0.46-r12 [2.0.47-r2]    
 
2.0.47-r2 is already installed, why would I want to downgrade? 
 

Expected Results:  
not have chosen to downgrade portage to an older release. 
 

Portage 2.0.47-r2 (default-1.0, gcc-2.95.3, glibc-2.2.5-r2,2.2.5-r7)
