can't install gnome

[Ray Phillips <r.phillips%uq.edu.au@localhost>]

I've downloaded the gnome package and its dependencies using 
pkg_fetch from 
ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/6.1.5/All and 
then attempted to install it on a NetBSD/amd64 6.1.5 machine with 
`pkg_add gnome' but it failed.  The last few lines of ouput were:

pkg_add: Warning: package `libgnomekbd-2.32.0nb17' was built for a platform:
pkg_add: NetBSD/x86_64 6.0 (pkg) vs. NetBSD/x86_64 6.1.5 (this host)
Warning in file 
"/usr/pkg/share/applications/Thunar-folder-handler.desktop": usage of 
MIME type "x-directory/gnome-default-handler" is discouraged

modern equivalent)
Warning in file

pkg_add: Warning: package `libgtop-2.28.4nb7' was built for a platform:
pkg_add: NetBSD/x86_64 6.0 (pkg) vs. NetBSD/x86_64 6.1.5 (this host)
pkg_add: Warning: package `osabi-NetBSD-6.0' was built for a platform:
pkg_add: NetBSD/x86_64 6.0 (pkg) vs. NetBSD/x86_64 6.1.5 (this host)
The Operating System version (6.1.5) does not match 6.0
pkg_add: install script returned error status
pkg_add: Can't install dependency osabi-NetBSD-6.0
pkg_add: Can't install dependency libgtop>=2.28.4nb3
pkg_add: Can't install dependency bug-buddy>=2.26.0
pkg_add: 1 package addition failed
#

which is curious since many packages seem to install and function 
properly despite the warning about them being built for 6.0 instead 
of 6.1.5.

What are my options now?  Is the best thing to try to install from pkgsrc?
