Rails Installation Error


I am trying to install Rails on my Max OS X 10.6.5.

I run the “gem install rails” command and it seems to stop short,
yielding a “File not found: lib”
message. There is no “Error” message but the installation just stops.

The command and the output are as follows…

if4it$ sudo gem install rails
Fetching: railties-3.0.3.gem (100%)
Fetching: rails-3.0.3.gem (100%)
Successfully installed thor-0.14.6
Successfully installed railties-3.0.3
Successfully installed bundler-1.0.9

Installing ri documentation for railties-3.0.3…
Installing ri documentation for bundler-1.0.9…
Installing ri documentation for rails-3.0.3…
File not found: lib

Do any of you have any suggestions as to what this means and what the
follow-up steps would be to correct it and complete the installation?

Thanks, in advance, for any assistance you can offer.

My Best,
