My short answer is: Dunno.  I build stuff from pkgsrc and it just
works.  (^&  The longer answer follows:

From _source_ (i.e., by hand) or from pkgsrc (i.e., where everything
should automatically sort itself out)?

It's not clear from this message (nor, as I recall, from your
original) whether you are using pkgsrc.

After the normal link pass, you mean?  I don't know; I wouldn't expect
that you could statically link an already-linked executable image.

If you are using pkgsrc, you shouldn't have to worry about this.  If
pkgsrc is screwing up, check the NetBSD bug repository to see if someone's
already send-pr'ed it, and if so, whether they have a solution or
workaround (and if not, you might send-pr your problem...).
