[Rubygems-developers] Readline relationship?

Hi,

I'm currently running a version of Ruby without readline support (yep,
Windows). When I run a "gem install" I get this:

C:\>gem install win32-ipc
Successfully installed win32-ipc-0.5.1
1 gem installed
Installing ri documentation for win32-ipc-0.5.1...
C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in

`run'
        from C:/ruby/bin/gem:24

The gem appears to have installed successfully, so for now I've just
been ignoring these errors. However, I'm curious about the relationship
between rubygems and readline. What does rubygems need with readline
exactly? And can it live without it?

If it _can_ live without it, I think we should consider a more elegant
way to deal with the LoadError.

Regards,

Dan
