I noticed that pkgin sometimes removes packages, but never (re)install them 
during a "pkgin fug" run.
Example from a recent pkgin-0.6.4nb1 run:

bash-4.2# pkgin up
pkg_summary.bz2                     100% 2019KB 504.8KB/s 361.6KB/s   00:04
processing remote summary 
(ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/6.1/All)...
updating database: 100%
bash-4.2# pkgin fug
calculating dependencies... done.
mysql-client-5.5.35 (to be installed) conflicts with installed package 
mysql-client-5.5.33nb1.
proceed ? [y/N] y

83 packages to be upgraded: x11-links-0.79 [?]

3 packages to be removed: dnscheck-1.4.1 p5-Test-Warn-0.24nb2 apache-2.2.25nb1

86 packages to be installed: p5-Test-Fatal-0.013 [?]

proceed ? [Y/n] y


It seems like pkgin doesn't reinstall the packages, which are the same versions 
as earlier?
(dnscheck-1.4.1, p5-Test-Warn-0.24nb2 and apache-2.2.25nb1 where all the same 
version installed, as in the latest pkgsrc binary distribution?)
>How-To-Repeat:
Simply update from a older stable branch of binary build packages

You need to have some old stable packages installed, that aren't a dependency 
to other packages nor should they change version between the stable branches...
