The dlopen/dlsym functions are built into libc on FreeBSD, so there's
no need for a libdl:


DLOPEN(3)              FreeBSD Library Functions Manual              DLOPEN(3)

NAME
     dlopen, dlsym, dlfunc, dlerror, dlclose -- programmatic interface to the
     dynamic linker

LIBRARY
     Standard C Library (libc, -lc)
