No doubt about it.

How that come that somebody could not have libyaml on some platform but 
would be able to compile libyaml bundled with psych? This argument seems 
moot. Or are you going to fork libyaml because of that?

It is even smaller if you don't bundle it and use the system one :)

Who are you referring to? If there is somebody like that, he/she should 
have probably some level of understanding, because it will be needed 
sooner or later.

I'll definitely look at nkf. Thanks for the tip. Also note that there 
are other bundled code, such as rubygems, rake, rdoc, oniguruma, 
minitest. But I am not sure why Ruby should use bad examples as a 
justification for bundling.

If the implementation will follow proposal 1) from Jeremy, then probably 
quite easily. But this is not technical question, if I can or cannot.

I like this guide

It is as cumbersome as compile Ruby from sources. If you don't like 
cumbersome processes, then there are packaging systems, rubyinstaller, 
RVM ...
