It is rebuilding farsight2 successfully ad infinitum.  Alan Barret's
patch does not seem to solve the problem (for some reason the patch
did not apply cleanly, so I applied it manually).  Following a
successfull build of farsight2, I still see

While debugging, I also discovered that pkg_rr had updated
pkgtools/pkg_install, after which I could no longer pkg_add newly
built packages using the system pkg_add binary.  For some reason,
pkg_rr didn't like my trick of chmod -x ing system binaries to run
pkgsrc's versions instead, and kept looking for /usr/sbin/pkg_admin
and /usr/sbin/pkg_info, so I symlinked them to the pkgsrc versions
(this is all happening inside a pkg_comp chroot).

I don't know if it is safe to delete pkg_install on NetBSD in order to
use the system version, after having installed some packages with the
newer pkgsrc version (the "marked as not for deletion" message scared
me, and I don't want to screw up my pkgsrc db by using incompatible
versions of the tools).

Now I am beginning to think that I have created enough of a mess to
justify nuking the entire pkg_comp chroot and rebuilding everything
from scratch, *sigh* (but perhaps I should first give Ian Leroux's
patch a try as well).

Thank you for your help.
