Until it's fixed, this bash script ought to fix this issue :

#!<prefix>/bin/bash

# this goes through alle the installed mysql versions
# and removes all links
while read -u 9 portName isActive
do
    while read -u 8 fileName
    do
        link=$( echo "${fileName}" \
              | sed -E -e 's/lib\///' -e "s/${portName}\///" )
        [[ -L "${link}" ]] && rm "${link}"
    done 8< <( port contents ${portName} )
done 9< \
    <(    port -q select --list mysql \
        | grep -v -F 'none' )

# this creates the links for a mysql version given in ${1}
while read -u 8 fileName
do
    link=$( echo "${fileName}" \
          | sed -E -e 's/lib\///' -e "s/${portName}\///" )
    ln -s "${fileName}" "${link}"
done 8< <( port contents ${1} )
