Sorry, I reply to a hundred year old post and take a hundred years to reply to you.
Hmm. I haven't seen that file libflashsupport_32.so in a while but I had to have both it and the libflashplayer.so in the mozilla plugin directory to get flash to work. Another mystery. Maybe I downloaded the 64 bit flash and got the files mixed up. But it worked. Later I found that the tcz install would not always work. And later I would not see this file libflashsupport_32.so and I would just put the libflashplayer.so which I got from Adobe in the /use/local/lib/mozilla/plugin directory not bothering to put it in /usr/lib as the readme suggested and that would be all flash needed. I vaguely remember reading something telling me to do this but I can't find that now and I can't find the files I was using, so I guess I'll never know. Sorry.
Lately it seems that libflashplayer.so needs to be put in /usr/local/minefield6/firefox-6.0/plugins. These things keep changing.
Now I take back what I said about the readme. It isn't so great... ...No, Now I take that back, the new tcz package for flash 10 works fine so the readme is great after-all...
I forgot to tell xpto09 to try installing the oss-alsa package along with the oss. Not that it matters now, it was such a long time ago.
