That's not the first thing to do, no.

Well, this begs the obvious question, did you remove or try to remove
the packages using pkg_delete?

There are also some packages that don't want to be removed once they
are installed, usually they start with pkg*.

You can do this a few times, assuming you're using a bourne shell:

# for pkg in `pkg_info | awk '{print $1}'` ; do pkg_delete $pkg ; done

You'll probably have to run through that a few times while it figures
out dependencies. You can use one of the "force" options with
pkg_delete, but I prefer not to.

When you're done, there might be 1 or 2 packages left that don't want
to get uninstalled, but this should be good enough to start over with
building or installing new packages.
