Yikes!
Well, those are all OSS projects. We should fork them, fix them, and
send
pull requests/patches

I’ve been trying to writing a lot of dubious cross platform command line
tools with ruby lately and have wanted to isolate the detection of
various
platform specific capabilities (playing audio files, accessing the
clipboard, launching a browser) to a gem:
It is by far the most hideous and embarassing gem ever - basically one
gigantic case statement. I should have called it the picture of dorian
gray. I’d briefly looked at ironruby 1.0 rc2 but couldn’t see an easy
way
to characterise it and haven’t got to jruby or linux at all yet.
I noticed that someone else has attempted to create something similar
with
sane (the homepage link from sane | RubyGems.org | your community gem host is broken so
i’m
not sure where the source really is).
It’d be awesome for the existence of such things to be unnecessary.
Mark.
Sure, using RUBY_PLATFORM is not good. However if you search thru Ruby
gems it’s used all over the place 
So until at least 90% of Ruby apps detect OS specific features properly
we need to keep RUBY_PLATFORM set to win32/darwin/linux depending on the
underlying OS. I guess some gems might be broken on JRuby on Windows
since they don’t check for “java”.
