If a port uses some version of a library via dlopen and we know about
it, we often list it like this

# via dlopen
WANTLIB += foo

often such ports use dlopen at runtime so that they'll work whether that
library is installed or not, but still need to be rebuilt if the ABI
changes, and without the "extra" WANTLIB pkg_add won't find the update.
