Hi - I get the following error when I run "ri" command.
I'm using Mac OS X Snow Leopard. I installed Ruby with MacPorts.

/opt/local/lib/ruby/gems/1.8/gems/rdoc-2.3.0/lib/rdoc/ri/driver.rb:405:in
`initialize': Permission denied - /Users/jon/.ri/cache/.doc_dirs
(Errno::EACCES)

  from /opt/local/bin/ri:19:in `load'
  from /opt/local/bin/ri:19

Can anybody help solve this issue?

First things first: does the file exist?
/Users/jon/.ri/cache/.doc_dirs
