for me what worked is:

grep libjpeg /usr/local/bin/* /usr/local/lib/* | grep Binary | awk
'{print $3}' | sort -u > /tmp/p1 

after that I have a list of all files that uses libjpeg (or at least the
almost of all).

another script.... gets the package list....
for i in `cat /tmp/p1`
do
    pkg_info -W $i  | awk '{print $NF}'  >> /tmp/p2
done

finally.............


portmaster -Bug `sort -u /tmp/p2`  builds all ports that have
libjpeg....

several hours later...  it all works....

Hope this will help.
