And like any binary releases, there are platforms that are missed/forgotten/not cared enough about.

Yes, binary releases are a convenience for users of common platforms, and not a catch all for every version of every relevant platform.

This is why the source is available. Implementation in Ruby, or any other interpreted language, does not guarantee compatibility. Not all systems have current interpreters or dependencies.

If I'm on a semi-obscure platform like Solaris or GNU/kFreeBSD I'd rate my odds much more highly with Ruby than with something that builds binaries.
