Problems with gem rdoc rspec

Testing RSpec
1

My gems, e.g. rspec, gets installed in:
/Library/Ruby/Gems/1.8/gems/rspec-1.2.2

(Note the extra /gems/ subdirectory)

When I run “gem rdoc rspec” the output is empty and the Files section
has errors:

file not found -/Library/Ruby/Gems/1.8/rspec-1.2.2/rdoc/License.txt-
file not found -/Library/Ruby/Gems/1.8/rspec-1.2.2/rdoc/Manifest.txt-
file not found -/Library/Ruby/Gems/1.8/rspec-1.2.2/rdoc/examples/
failing/README.txt-
file not found -/Library/Ruby/Gems/1.8/rspec-1.2.2/rdoc/TODO.txt-

(Those are the only files in there. Note the lack of /gems/
subdirectory)

Do I need to add /gems/ to my GEM_PATH? I didn’t think that’s how it
works, and my other rubygems build their rdocs fine.

Or do I need to set a different path variable to set this up?
(GEM_HOME? I tried that and it didn’t seem to help.)

Thanks for your help,

My environment:

$ echo $GEM_PATH
/Library/Ruby/Gems/1.8

$ more ~/.gemrc
