$> gem install hoe

(installed hoe-1.10.0 and dependency rubyforge-1.0.3)

$> spec --help

Usage: spec (FILE|DIRECTORY|GLOB)+ [options]
(etc., etc., etc.)

Seems like "gem install rspec" does not install the dependencies.
Not sure if it is exclusive to JRuby on Windows... other OSes not tested.

Answer 1

Does gem install rspec --include-dependencies help? It wasn't default until a later version of Rubygems, perhaps jruby isn't quite up to snuff.

Answer 2

Works for me with JRuby trunk:

$ jruby -v
jruby 1.3.0 (ruby 1.8.6p287) (2009-03-15 r9415) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_07) [x86_64-java]
$ jruby -S gem install rspec
