Did you try ``make update''?

That's how I always build/install/update packages.  (You don't need to
have it previously installed; it deletes any obsolete packages and cleans
up the ...pkgsrc/*/*/work directories that it uses.)

That doesn't mean that it's always wrinkle-free: Critical libraries
sometimes get updated, and packages start to insist on the updated
version.  Further, especially when NetBSD isn't close to a release or a
patch-release, you can sometimes get a devastating effect: After pkgsrc
deinstalls every ``obstructing'' package and begins the rebuild process,
some package along the way may fail to build cleanly.  Then you can be
left with many of your more valued packages de-installed.
