NetBSD version mismatch warning while installing packages

[Emmanuel Kasper <emmanuel.kasper%openforce.com@localhost>]

Hello
When installing binary packages from the PKG_PATH
ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/5.0.2_2011Q2/All/

I get the following warning:
pkg_add: Warning: package `pkgin-0.4.2nb2' was built for a platform:
pkg_add: NetBSD/i386 5.0.2 (pkg) vs. NetBSD/i386 5.1.0_PATCH (this host)

Since I have installed the package compat50 can I safely ignore this
warning ?

pkg_info -a | grep compat
netbsd-compat50-5.1 Compatibility package for 5.0.x binaries
