Rails install problem

Hi, all.

I'm having a problem installing Rails on Mac OS X 10.6.8. When I issue the command `$ sudo gem install rails` I get:

<code>

[Tue Nov 08 23:36:17 dobbin@darkstar:~ ] $ sudo gem install rails Password: /usr/local/rvm/rubies/ruby-1.9.3-p0/bin/gem:4: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777 Successfully installed rails-3.1.1 1 gem installed Installing ri documentation for rails-3.1.1... Installing RDoc documentation for rails-3.1.1... [Tue Nov 08 23:37:10 dobbin@darkstar:~ ] $ rails Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

</code>

Is the `warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777` the culprit?

Any help appreciated,

Cheers,

After banging my head against the wall all night, I ended up installing it via MacPorts.
