Rails - Oct 2005 - Got a strange RDoc error while installing a fresh env of RoR tonight

I started a new fresh install of ruby on rails tonight in a Sandbox (using
--prefix on all the configures, and then editing my bash paths to make sure
I was using the Sandbox). I install Ruby 1.8.3 and then RubyGems 0.8.11. I
then used gems to install rails and got this RDoc error:

*************
$ gem install rails

Local gem file not found: rails*.gem

RDoc failure in lib/rake.rb at or around line 1421 column -517651418

Before reporting this, could you check that the file
you''re documenting compiles cleanly--RDoc is not a
full Ruby parser, and gets confused easily if fed
invalid programs.

The internal error was:

ERROR:  While executing gem ... (RuntimeError)
    unget past beginning of file
*************

I then ran `gem install rails` and did not get the error again. Any idea
what I''m doing wrong?

I''m on OS X 10.4.2 if it makes any difference.

Thanks,
