I checked out the sup git repo and after fighting a bit to get all the
libs I needed installed (it's a bit wonky since I'm letting both
rubygems and BSD's pkg_add manage different ones).
$ ruby -I lib -w bin/sup

The problem here is that you are asking for libc.so.6 which OpenBSD
doesn't have (on my 4.3 system I see ["/usr/lib/libc.so.41.0",
"/usr/lib/libc.so.43.0"]). A patch:

end
LibC.setlocale(6, "") # LC_ALL == 6
Now after doing that I still can't get sup to go. It doesn't seem to
like curses for some reason:
--- ArgumentError from thread: main

I noticed when trying to install sup via gems (before giving up and
running the code directly) that it died on compiling curses support
for some reason:
I installed the OpenBSD ruby-ncurses package instead and hoped all was
well. I am just learning Ruby, but the fact that sup gets past
`require 'ncurses'` means that ncurses should be installed right?

Stop in /usr/local/lib/ruby/gems/1.8/gems/ncurses-0.9.1 (line 92 of
/usr/share/mk/sys.mk).
Anyway, it shouldn't matter that the gem can't install because the
ncurses.rb I have installed in site_ruby is newer than the ncurses.rb
from the gem, judging from the version line. I don't know what to make
of this since at all. I'm not familiar with Ruby yet but if you could
point me at a right direction I will probably be able to figure this
out.
p.s. sorry for the null message just now. Sup doesn't work (yet) so I
was going to write this message in `mail` before I realized that was a
terrible idea but my finger slipped.

Someone else just reported this problem too. I wonder whether the best
solution is your patch (remove the .6) or the patch I was thinking of,
where we special-case BSD to look for libc.so.43. Does anyone have any
suggestions?

I... think so. What's your TERM environment variable set to? Do other
(color!) ncurses programs work?

Do you have both ncurses and ruby development libraries installed? I
know what they are in Linux world but not in BSD land.

Yeah, I would ignore the gem issue for now. I suspect that at this point
it's a matter of tricking the 1970's technology that is ncurses into
displaying color on your particular environment, by trying different
TERMs and terminal emulators.
