I'm using a 1.6.1 custom kernel with the
1.6.1 userland binary distribution sets.
========================================================
I updated pkgsrc via AnonCVS:

# cd /usr/pkgsrc
# cvs update -dAP

After update "make info" in any package fails:

robin# make info
pkg_info: unknown option -- K
usage: pkg_info [-BbcDdFfIikLmnpqRrSsVvh] [-e package] [-l prefix]
                pkg-name [pkg-name ...]
       pkg_info -a [flags]
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/www/apache
========================================================
I updated pkgsrc with a sticky tag via AnonCVS:

# cd /usr/pkgsrc
# cvs update -r netbsd-1-6-1 -dP

and "make info" works as expected.
========================================================
The implication is the latest version of pkgsrc can't
be used with NetBSD 1.6.1 branch.

How closely does the pkgsrc netbsd-1-6-1 branch track
the main trunk of pkgsrc?

Thank you,

Conrad
