FreeBSD's libc provides dlopen(), dlclose(), etc-- there's no need for a separate libdl to do dynamic loading.

fdatasync(2) is a cheaper version of fsync(2) which does not try to update filesystem metadata; using soft updates with FreeBSD's  UFS2 filesystem already provides most of the benefits.  So you don't need that either, just call fsync() instead.
