Enabling Adobe flash in NetBSD 7.0 amd64

[DaBSD]

I've installed adobe-flash-plugin11 from pkgsrc (although I had to disable checksum test, as the package was available for minor number 554 and the checksums in the latest distinfo file were for 548) and at the end I got the following error:

===> Install binary package of adobe-flash-plugin-11.2.202.554
nspluginwrapper: no appropriate viewer found for /usr/pkg/lib/netscape/plugins/libflashplayer.so

The same response as in this case:

bash-4.3# nspluginwrapper -v -i /usr/pkg/lib/netscape/plugins/libflashplayer.so
*** NSPlugin Viewer *** ERROR: /usr/pkg/lib/netscape/plugins/libflashplayer.so: wrong ELF class: ELFCLASS64
nspluginwrapper: no appropriate viewer found for /usr/pkg/lib/netscape/plugins/libflashplayer.so

Googling this issue made me think there has to be available a viewing program like ns-flash, but it's already deleted from pkgsrc. I've got the following flash utilities installed:

bash-4.3# pkgin list | grep flash
adobe-flash-plugin-11.2.202.554 Adobe Flash Player Browser plugin
flashplayer-0.4.10nb7 Standalone open source Flash(tm) player
libflash-0.4.10nb9 Open source Flash(tm) library
libflashsupport-1.1 Additional Interface Support for Linux Flash Player
swfdec-gnome-2.28.0nb40 Gnome flash player and thumbnailer using swfdec

... but they seem to be of no help. How can it be worked around? Can this problem originate from the fact that my 64-bit OS has emulation linux32? That's just the way I got it installed...
