You can use ldd on the binary to see which libraries it's linked against.

Also, if you pkg_delete each of the packages, it will refuse to delete them
if they're still used by other packages, and it will tell you which packages
are using them.

(You can probably do that second one with pkg_info as well, but I don't
know the syntax off the top of my head)
