You could try filtering things you know aren't interesting from the
noise. For instance, adding "| grep -v ^pkg-plist" would throw out the
obvious direct dependencies. Or send the original output to a file,
and start greping through that. However, you provided a pointer to a
better solution below.

Yup. Patches welcome :-); it looks like more than a one-evening hack.
For now, try this in bash:
for l in $(ldd -f %p\\n $(which galeon-bin))
do
echo $l:
strings $l | grep libpng | sed 's/^/ /'
done
Libraries that aren't found will generate ugly results from this....
