Using nspluginwrapper on amd64/4.99.55 fails

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I just tried using nspluginwrapper to add flash support to a native
firefox on NetBSD-4.99.55/amd64.

The instructions in nspluginwrapper's description are:
        To install the Linux flash player into a native Firefox browser:
          - Also install multimedia/ns-flash and multimedia/libflashsupport
          - Run "nspluginwrapper -i 
/usr/pkg/lib/netscape/plugins/libflashplayer.so"
          - Run Firefox

The second step produces an error:
# nspluginwrapper -i /usr/pkg/lib/netscape/plugins/libflashplayer.so
/usr/pkg/lib/nspluginwrapper/i386/linux/npviewer.bin: error while loading 
shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such 
file or directory
nspluginwrapper: no appropriate viewer found for 
/usr/pkg/lib/netscape/plugins/libflashplayer.so

However, npviewer seems to be fine:
