Comment:

 Have you already made sure your port definitions are up to date and that
 there are no outdated ports?
 {{{
 sudo port selfupdate
 port outdated
 sudo port clean mldonkey outdated
 sudo port upgrade outdated
 }}}

 If that doesn't fix it, then please attempt to discover what installed
 port still wants to use libpng12. Try a brute-force search for "png12",
 such as:
 {{{
 sudo grep png12 -r /opt/local/{bin,include,lib,sbin} 2>/dev/null
 }}}
 For each identified file, use "`port provides`" to see what port it came
 from. That port probably needs to be rebuilt. You can rebuild a port using
 "`sudo port -n upgrade --force`" but please also let us know what ports
 were identified, so we can see if we need to increase their revision.
