Here,

I built Irssi from latest SVN and I got B-itchX to run in OS2008.
Sorry *****x's, no plugin support in *****X (be thankful I figured out how to make it compile :P)

P.S, like all builds of irssi, this one likes to segfault sometimes. Remember X-Chat is available for tablets too (google xchat chinook), pidgin and rtcomm beta support irc however badly. Enjoy.

Attached.
(Yes, I know *****X screenshot isn't promising but I promise I was connected to a server before! )Yep, i'm connected to #maemo via B-itchx fine so it works great.

Btw, the first 54+ or so ****ers in this moment of time who cannot even post thanks but click download link, you are welcome. Mother****ers.
