Ports aren't really set up for incremental development the way you are
doing.  For normal use they're compiled one time into a package and then
installed.

Where you need to modify the port, generally you'ld get into a cycle of
compile, modify, clean, re-compile from scratch, rinse, repeat ...  For
the vast majority of ports, the compilation step takes only a few
minutes on reasonable hardware so this isn't really a huge burden.

Bigger and more complex programs will need an iterative approach as you
are doing to develop local patches and then a final clean and complete
build.  You can often just run make from within the $WRKDIR of the port
to incrementally rebuild after code changes, or you can remove the
.build_done file and rerun the build target of the port.
