This is because the under appreciated FreeBSD make system does a *lot* of work
for you.
- You need libutil: /usr/src/lib/libutil or (probably faster), see which
functions from libutil date uses and re-implement them.
- Resolve header issues in the above source files
- And then it's most likely easiest to use cmake or autotools on linux to
compile.
