All, Vim does not currently support integration with Ruby 1.9, but it's on the list (see :help todo).
Masaki Suketa supplied a patch[1] to the vim_dev mailing list in July 2009, under the subject line "Patch for Vim with Ruby 1.9". Using this patch, I'm able to build Vim with support for Ruby 1.9 (on Arch Linux), as well as Ruby 1.8 (on Fedora 12 Linux). The Ruby-based plugins I use (LustyExplorer[2] and LustyJuggler[3]) work fine Ruby 1.8 and Masaki's patch. With Ruby 1.9, LustyExplorer is throwing an exception[4], but I think it's a problem with the plugin and the changing Ruby language definition, not a problem with integrating Ruby into Vim. Until Ruby 1.9 is supported in Vim, it will be more difficult for plugin authors to try Ruby 1.9 and fix any problems. Arch Linux uses Ruby-1.9, so the Arch packager for Vim has disabled Ruby integration[5] pending a Vim patch that works with Ruby 1.9. This leave Arch users somewhat out in the cold for Ruby integration. Is Masaki's patch ready to be incorporated, or is more testing required? Masaki had done testing with multiple versions of Ruby, including 1.8.7, 1.9.1, and 1.9.2dev. It's working for me with Ruby 1.8 on Fedora, so it looks harmless for Ruby 1.8 users, while allowing Ruby 1.9 users a chance to more widely exercise Ruby-based plugins and shake out compatibility bugs.
