This appears to be the opposite of a upgrade.  He has a package that 
wants the OLD slotted version of libpng not the NEW slotted version.  If 
I understand that correctly, he has already done the upgrade but now 
something needs the old package installed in addition to the new one.

OP, my thinking is this.  Be prepared for some packages to rebuild when 
you run revdep-rebuild.  Part of me says that there won't be any but one 
can never be certain of these things.   Also, when I did my upgrade I 
had no GUI until it rebuilt the packages.  Again, one can never be 
certain of these things.  I would do this:

emerge opera
run revdep-rebuild -i and say a prayer if you think it will help.
emerge -uvDNa world and hope it comes out clean, provided it was clean 
before you started this.

Wouldn't hurt to have a second puter around to get help here if you run 
into trouble.  ;-)
