Hello,
I'd like to be educated a bit on how rubygems in 1.9-p0 works together
with
$LOAD_PATH, because it it seems slightly inconsistent to me, for
instance
mocha 0.9.5 is installed, but not in my load path:

$ gem1.9 list | grep mocha
mocha (0.9.5)
$ irb1.9
irb(main):001:0> $LOAD_PATH.grep /mocha/i
=> []

irb(main):002:0> pp `gem1.9 list`.split("\n").select{|g|
$LOAD_PATH.grep(/#{g.split(" ").first}/) == []  }
["addressable (2.0.2)",
 "archive-tar-minitar (0.5.2)",
 "cgi_multipart_eof_fix (2.5.0)",
 "data_objects (0.9.11)",
 "do_sqlite3 (0.9.11)",
 "extlib (0.9.10)",
 "gmailer (0.2.1)",
 "meta_project (0.4.15)",
 "mime-types (1.15)",
 "mocha (0.9.5)",
 "mongrel (1.1.2.0.1, 1.1.2)",
 "open4 (0.9.6)",
 "plist (3.0.1, 3.0.0)",
 "ruby-yadis (0.3.4)",
 "stomp (1.0.6)",
 "textpow (0.10.2)",
 "thin (1.0.0)"]

Any reason why these aren't put into the LOAD_PATH?

And similary the gem() command doesn't like spaces in the version
argument:
irb(main):001:0> gem 'mocha', '>= 0'
NoMethodError: undefined method `<=>' for nil:NilClass
from <internal:gem_prelude>:249:in `push_gem_version_on_load_path'
from <internal:gem_prelude>:14:in `gem'
from (irb):1
from /usr/local/bin/irb1.9:12:in `<main>'
irb(main):002:0> gem 'mocha', '>=0'
=> true
irb(main):003:0> require 'mocha'
=> true


So, my question is; what's the secret sauce needed here?

Cheers,
JS
