Is installing from a package an option for you? In this case
only the run dependencies will be installed, the build dependencies
will be left out. I can imagine that some software vendors put
everything on the build dependencies list they typically find
on developers' Linux systems (git to check out code, a "custom"
compiler, maybe a whole document processing system for the creation
of the documentation, and so on), but on FreeBSD those maybe are
not needed, so using a package might not "pollute" your system
with stuff you don't need.

Usually a port _does_ have configuration options to avoid this,
but as I said: If the maintainer considers certain software
essential for building, the required stuff is not optional
anymore - no matter if the programs in question are _actually
being used_ or not...
